Has anyone on here got one fitted and whats it like? I am tempted by the twin dump pipe and wonder if anyone has any personal experience to share with me? Delivery time, looks, sound, the whole lot!

Tim

RobJenks

Yeah Tim , I have the BPM twin dump pipe and the BPM enlarged inlet pipe.
This efficient breathing necessitated the purchase of the Possum Link - Now that is another story!
I can fully recommend the BPM components.

WALKER

Tim

Try giving Mike a ring at Scoobymania, they have just produced their own twin dump downpipe and it looks and sounds bloody lovely.

Paul

Mike Tuckwood

Yep, I had a BPM twin dump , full system.

Took over 5 months from ordering to fitting, wrong d/pipe sent after 4 months, right one came over a month later.

Sounds and feels good, D/pipe is Ok rest of system was deteriorating rapidly after 6 months of use.

The system is mostly mild steel pipework, this was flaking heavily after only a short period of time, even the tailpipe which was Stainless was badly corroded after 6 months.


We are releasing our full 304 grade Stainless Steel 3" system, straight through de-catted with twin dump down pipe mid October.

Great having a go at other suppliers when you fail miserably to get your own house in order eh

Tim Bomford

I am keen on the look of your pipe Mike but Greg has quoted me what I thought was a good price for a stainless pipe. Yours looks by far the nicest and I was going to go with yours....I shall wait to see if Greg has anything to say here as we all remember what he was like when he 1st started posting I do not want a long wait for this to arrive so if anyone else has comments to make I would appreicate it.

Tim

Mike Tuckwood

Sunilp.

<I>That was really productive!

If you want to have a dig, open a new thread and tell everybody what happened.....making snide comments and misleading people that you have been unfairly treated is unfair and undeserved!

Our house is not perfect, but the service we provide relies on other peoples houses; don't hang us for their errors.</I>

My comments were genuine as I have direct personal experience of relevant to the question posed.

Anyway....... Tim, give me a ring on 0115 913 3199, I will outline the differences and costs of our system/down pipe if you like?
(Apologies for the above outburst).


Regards

Mike.

I'll call you today Mike. What is your delivery time, any in stock?

Tim

Interesting post Mike.

Considering the sheer volume we do of the TD38s Twin Dump worldwide might we state your "appraisal" and your "results" showcase your ulterior motive. Sad ,pathetic and manipulative are words that spring to mind.

The HPC coat utilised is far superior in a salty environment compared to Stainless Steel.

Mike Tuckwood

None in Stock, jig being made from the prototype which has been on my car for the last 6 weeks undergoing 'field trials'

Production/stock should be 2nd week in October (approx. 2-3 weeks max).

And it sounds GREAT! Very deep almost V8 type note and sort of on the louder side.

<I>Oops, just noted Gregs reply above.
Hi Greg, Tim asked for experiences and I gave him mine. I remarked that your downpipe was decent, given that it was only mild steel (HPC coated).

High temp's at the D/Pipe mean it is less vulnerable to corrosion anyway. My comments on the rest of the system are genuine and correct, the stainless was heavily corroded after 6 months (1/2 a UK winter) and that can be confirmed by many people that saw it in that condition.

The mild steel pipework up to the back box <B>was</B> flaking slabs of corroded metal prior to me selling the car, it didn't look like I would expect at that age.

This is why our system is Full 304 grade austenitic stainless steel and will carry a 25 year guarantee against corrosion.</I>

I have to back Mike up on the corrosion issue... the corrosion to the backbox was unacceptable considering the short time the system had been on the car. I am fairly sure (not 100%) I've seen another early BPM system on a car in a similar state.

I understand BPM has now decided to coat the entire system to reduce/prevent such corrosion... this shows that they do respond to feedback, it's just a shame they didn't foresee the english climate related problems before sending their aggressively marketed product over to our shores.

Interesting...

I thought that silencers usually rotted from the inside out... are BPM back boxes now HPC coated internally and externally?.

I've never had an exhaust silencer rot through in less than two years, and most of my trips are short distance, which tends to accelerate corrosion. This is with a normal aluminised/zinc plated mild steel system a la quickfit...

Cheers,

Alex

sunilp

Mike,

I never mentioned anything above about being mistreated, snidey or whatever etc etc, i only posted that you should get your own house in order before critcising other suppliers. You have TRIED to put those words into my mouth above and they are your emotions and thoughts and, therefore, cannot be mine.
You should tread carefully if you want to avoid joining Jeffrey Archer in a courtroom near you.

When i have something to say i will say it in whatever detail and depth i want, wherever i want, if i feel anyone else can benefit. I will not seek your or anyone elses permission.

So please stop throwing your toys out of your pram - I can see that all of your posts have been consistently 110% constructive - like your dig at other suppliers of octane booster or AP brakes to name a couple - certainly no way to operate a business but then i have already learnt the hard way that you dont know how to operate a business anyhow.

Sunil, we have refunded you in full for the HKS gauge that the Royal Mail lost in transit to you, (which we were lucky to obtain in the first place).

Pursue your aggressive posts being Anti Scooby Mania at your leisure in your attempts to punish us for that loss if you wish

It matters not to me how rude or insulting you are (within reason), if it makes you feel more comfortable blaming us for the loss by the courier then go ahead.

As you will see from comments from other respected BBS contributors, I told the truth and that has been confirmed, no pursuit, simply the truth.

Why do you feel your digs at both posts I have made today are helpful? They have both been sideswipes at me and have not helped the person/people who posted the threads.

<I>In the interests of not boring other BBS users to death, if you wish to reply or take this matter further, drop me a mail or give me a ring at your discretion?

I will gladly talk to you if I can drag myself away from messing up both of my badly run businesses)</I>

To answer the questions in order the Twister Backsection is Full HPC both inside the muffler and outside.

The GT Muffler is 304 Stainless polished.

WALKER

This is all very interesting and can only say that i can back Mike up.

I tried to order a BPM Twister backbox myself, from ********in Manchester. I finally managed to speak to them after many attempts of promised calls back.
I explained that if they had one in stock i would have it off them, as i was taking part in the Wales trip at the weekend so would need it quick.
They said that they did have one in stock but would just check to make sure and give me a call back in the morning.
I`m still waiting for that call, which must be a least 3 weeks ago.

Due to this i have now ordered a Back box of Scoobymania, which i will receive in 2 weeks time.
I have bought various bits and pieces of Mike and can only say that the level of service and quality of products are second to none and they don`t rip you off!

Paul

Tim Bomford

Yes..I'm sorry to have stirred something up here, I only wanted opinions not arguements.

R19KET

Well, I've tried several exhaust combinations, and so far, the BPM twin dump, with the HKS Hyper, have given me the best results.

This combination is better suited to those who are looking for mid~top end (track bias). The BPM d/p does seem to lose some low down torque, but comes into its own from about 4k.

I can't comment on the rest of the BPM system, but the HPC'd d/p is still in perfect condition.

Mark.

I'm sure that when Scoobymania offer their system, it too will be tried, and tested.

BPM

Walker,

I guess all we can say is that it upsets us that one of our dealers didn't follow through but this is not an indication of stock levels being available.
Sometimes we have had to deal direct into the UK to fulfill urgent requests, although it is not company practise.

Suffice to say if anyone on this list has problems in acquiring stock in the UK , please drop us a line and we will do everything we can to help out.

Tim,

I think this thread has been extremely enlightening to say the least and we feel comfortable the "truth" has been revealed rather than biased opinion forming fact.

Still it is amazing that the BPM TD38 HPC on Mike's car showed "so called wear" and Marks, after close to a year of testing is in pristine condition.

BPM

Mike Tuckwood

Greg.

If you read back, I never said the downpipe was bad or wearing badly.
Absolutely everything else that was attatched to it was though.

Mike.

R19KET

Mike,

But then you sold that old rust bucket, and bought a new one

Guys, I wish we could stop all this bickering. It really does no one any good, and certainly doesn't help Tim.

ALL companies, however good, suffer from the occational problem. It's how they resolve the problem, that sorts the good from the bad.

From experience, both Scoobymania, and BPM, go out of their way to offer the best service possible, but sometimes things just contrive against us

Enough supping up to two of my favourite suppliers

Mark.

CraigS

Mark,

I have watched this thread grow and thought exactly that.

For the record I have the full BPM GT System and I when in my purchasing cycle I did not choose it soley for performance aspect over other options available.

Let me tell you Australia it appears has far more options than the UK. Every tuning company is a Subaru Specialist

The reason I chose the BPM GT system was strongly based on quality of workmanship, the welds, finish, different hanger mounts and adjustable height of exhaust so I didn't have to scrape whilst entering my driveway.

Other factors included the ability to swap from a catless to cat system via a TorqueTight for emmision tests was also another feather in the cap for the system. This was an excellent addition to the full exhaust system so no cutting of the pipe had to be done for the cat/catless swap

And finally, because I know the attention to detail in respect to different turbos matching has led them to be the most respected choice in a country which has so many WRXs , there are grandmothers driving around 500hp beasts.

So in conclusion the BPM system I purchased was based on calculated decision making since being my field we do not rush into things.

Let me also say in conclusion this bbs is quite viscious.

Still pondering load points.

I have a full BPM system on as well - dont know which one - as Regal autosport in Southampton did not know - just called BPM twin dump!

I am happy just for the sound alone!

Just wish I could get a cat replacement pipe in the UK - I will need to resort to getting a special one made up? as nothing fits as standard to the downpipe - just want to be decatted to get flames out of the back

CraigS - are you saying that catless pipes are available for the BPM system in Australia?

Greg - do you know which systems were sent to Regal in the UK - always useful to know exactly what system I have - mail me off line/

Also as soem of the BPM customers will know - as a matter of good faith BPM is giving us a free rear Twister tail pipe - thats not bad!

CraigS

Steve,

The GT system I purchased was the new range when BPM chose to go full HPC coat. This alone was worth any wait.

As to my system it breaks down like this.

BPM TD38 Downpipe , if you have an Sti or VF Turbo you get the TD38s which has a longer tongue on the bell mouth and ensures a seal between the wastegate and turbo gases.

The Mid Section breaks up into 2 components

The Viper Resonator which is actually incorporates the Twister flow chambers. This is fantastic in my opinion for not only quietening the system (I am married)
but also stops drone due to the exhaust gases being spiralled out of the exhaust.

The Cat/Catless part can be purchased as an upgrade option . So you get a cat and also a straight bit of pipe that slots over the main centrepipe. Perfect for dodging those emmmision boys.

The Backsection is the GT muffler. One thing that wasnt mentioned was the fact the system is full interchangeable with the standard Subaru system even as 3" pipework.

I just checked the BPM website and it doesnt appear they have the new mid section on there yet, although the GT system is as per the site.

I don't think you have by the sound of it , the 2 bolt flange setup since I know for a fact I can replace the components with the standard Subaru ones and all the BPM parts fit straight on.

I would email BPM and ask them since this must have been awhile back.

Craig S

Thanks - I will check how many flanges there are on my system - mine was a sti 5 with vf28

I think mine was a J series system - whatever that means - but I could be wrong? - the dwonpipe is HPC coated but that is all.

I asked Greg about the catless pipe and the commnet was that this would not improve performance - I am not concerned about this - just being childish and want FLAMES!

May be worth waiting - as I should get the new silencer - then I just need to sort out the center part - as there seems no need to change the downpipe

I didnt notice any performance difference on fitting the exhaust system - but could hear the turbo better as the heat shield was removed - then again the car was linked up at that point anyway - and the mapper - Bob Rawle said that the exhaust had made a 'difference'

Stef

Sheesh!
If you want REAL power without all the hassle, sod them both and get a Scorpion!

Stef.

R19KET

Stef,

This was turning into a serious technical thread, and YOU come on, and start your comedy routine

The BPM twin dump is the third D/P that I've tried, and given me the most power so far (track bias). As for the build quality, it is by far the best. Attention to detail is first class.

You Aussie guys are very lucky, you currently do have a much wider choice of tuning products, but at least we know how to use them properly .

But best of all, we have Bob Rawle (BR Developments). Seems your tuners are pretty partial to his ecu maps .

So we may be buying some of your tuning products, but most of your cars (Link) are mapped over here

Thanks for the spin Mark My STi seemed like a sack of $hit by comparison on the way home! Too quiet and far toooooo slow.

Tim

Tim Bomford

Well here is a bit of an update (not that anyone probably really gives a $hit!). I finally decided to give BPM a chance after talking to Greg (eventually - bloody Olympics jammed up all Oz phone lines). From saying yes to Greg and actually ordering the pipe, it took exactly 1 week to get here. It arrived today and looks <B>really</B> good I must say. I am having it fitted on Wednesday and hope it sounds as good as it looks. For anyone worried about delivery times....all I can say is I am impressed so far with BPM (and Greg- thanks). One happy customer
