Hi all,

I'm in the process of acquiring (payment on way to owner) myself a prodrive sports cat, but it needs new straps to hold the lagging in place. Where can I get some of those from and what the heck are they called..?!! I don't fancy messing around with the lagging banage stuff, so intend to use the included jacket, so will just need the straps.

Also, where can I take my new cat and my car to get it fitted..? Ideally somewhere not too far away (I'm in south east Kent) and that can overcome any issues that may arise (I've heard of spacers being needed) without sucking air through their teeth.

Finally do I need to decat the up pipe as well for decent results..? I already have a decat centre and am unresonated.

Looking forward to this and my "soon to be fitted" green panel filter.

Cheers,
Nige.
MY03 WRX.

 

Will these do the job..?

your may also get overboost with the sports cat on and cell light may come on, my sti did i had it remapped though and now its ok.

you may need a spacer it depends what the sport cat you have bought, if it has come off if wrx will be ok (tdo4 turbo) if sti you need spacer, due to the the cat sitting in the turbo housing (vf34/35 turbo)

change up pipe as well as the same time saves you doing it again later and everything having to come off again.
well worth doing though makes big difference !

 

'03 sports cats dont have lagging, thats the earlier inferior bug eye type.

My 03 STi has lagging (jacket) around the cat.
According to Mike Wood in an earlier thread, it wasn't inferior? If it is - why?

I think that I may have spoken to Mike about sports cats on that thread. Im sure that it was only the earlier type that was lagged. I will come back to you.

When the warranty ran out on my MY03 WRX Stealth Wagon I went for a Hayward & Scott 100 cell high flow down pipe (only 2 BHP loss over decat pipe & MOT friendly)



H&S Up pipe




H&S Centre pipe straight through



Already have short section from PPP & Backbox.



Followed by a Tek3 re-map with Pat Herborn to get everything flowing nicely.

Resulting in :-



290bhp up from 252bhp (PPP)

275lbft up from 263lbft (PPP)

Boost 1.3bar up from 1.2bar.

I am a happy bunny

Mark,

Some very nice figures there.
Seems very similar to the route I'm going/sliding down...!!

Currently got H&S decat & deresonated centre sections and a WRSport backbox on so far. Just acquired a prodrive sports cat to go on soon. Next on the list will be H&S up pipe (seems a good idea and to get fitted at same time as DP), Green air filter (already waiting to go in), then it'll be an uprated fuel pump. Not sure if I need to change my intercooler pipe yet, got some reseacrh to be done on that. After that's all sorted, it's off to the much-praised Mr Rawle for mapping.

I'll be a happy bunny if I get figures like that. I'm cheesed off with getting blitzed 60-110mph on straight stretches of tarmac by all and sundry.

 

Mark,

How much were the high low dp and the up-pipe ?

cheers

The bugeye version with divorced dump pipe is poorly made in terms of pipework lining up with the turbo wastgate and esp. the turbine exit.
I've not heard anything wrong about the blobeye version (cast bellmouth with outer lag jacket).
The newest version has an internal jacket and doesn't need extra lagging.

Nick

 

i've only ever seen prodrive downpipes with the twin dump pipes, not seen a bellmouth before

is this one with an internal jacket? assumed the guy had taken it off to polish the nuts off it?eBay.co.uk: Prodrive Hi-Flow Cat / Sports Cat (Impreza WRX new-age) (item 290053088421 end time 30-Nov-06 19:09:23 GMT)

 

Very interested in this topic.

The PPP cat does use the second pipe for the waste gate which is in the face of the normal bell-mouth units, but I doubt it makes much difference.

You can get various 'blankets' to wrap the cat from Demon Tweeks.
Also the excellent priced TSL sport cat has a very neat blanket with it, but is only available in 2.5 inch outlet. (I need a 3'')

The H&S unit can be had in either size.

I think all the manufacturers use the came 100 cell cat anyway, they simply weld one into the decat pipe having cut a section out and adding tapers to suit the cat/pipe diameters.

Someone started a group buy a few months ago for the Ninja and the H&S pipes at significant savings when over 10 customers.

Graham

 

hoskip thats the same downpipe thats on mine, i paid £150 for mine so anything around that will be reasonable ,they are quite rare.worth buying and saving (as other post 0 until remap.

 

911 why do you need 3 inch ?

 

Tuned to 380 bhp and (once) 407 bhp.

You need a 3'' all through over about 350 bhp to avoid back pressure from the big turbo needed for the power.

2.5 is fine for upto 350 ish.

Graham
Just to show off: sorry-
DropShots Day

 

makes sense mines about 330

 

They were bought & fitted as part of this "Group Buy".

https://www.scoobynet.com/group-buys...group-buy.html

High flow dp £425 + vat

Decat up-pipe £90 + vat

Centre section £60 + vat

Fitting £55 + vat

H&S are not far from me so there were no carriage charges & Xtreme @ Boreham did the fitting.

Mark

 

Hmmm.... ok, so what's being said here is that the older prodrive sports cat with the external kevlar jacket isn't much good because it's poorly made...???

If that is the case, can someone show me where I can locate the newer type Prodrive cat or one of the H&S/TSL sports cats for sub £200 for a NEW AGE wrx please...?

 

You wont get a TSL thundercat for sub 200 unless its a used one.
But tbh you get what you pay for. I had mine on my 03 WRX over two years before my first MOT and it sailed through no problems. I wanted my car road legal from the first mods.

 

I am having a sports cat fitted in my 3" centre section on Monday,cutting a section out and welding a 100 cell cat in,£150 + VAT.

 

Here's the first version of prodrive sports cat with split pipework:



The blobeye version with cast bellmouth and splitter plate:



The latest verison is as per the blobeye but with integrated heat shield.

Here's a VF35 exhaust housing matched up to the Mk1 version- the picture doesn't quite do justice to how far out the housing is offset with the entrance to the downpipe tube.



Nick

 

Merv I was going to go for the centre cat but then these posts made me have a rethink. Will you have any issues with getting it hot enough come MOT time? I didn't want to have to fly up & down the road outside the garage till he's ready to stick the probe up my back end.

Also saves the hassle of swopping down pipes or double cat centre sections that some garages use.The risk of snapping studs & getting a gas tight seal each time is not worth it IMHO for the sake of 2 BHP.Also if you fail a roadside check you have all the hassle of another visit to the garage to get your papers stamped.

Mark

 

It is very hard to get the centre cat hot enough in line with the MoT routine.
This is why cats are shielded in stock form to keep them hot, and wrapped form on aftermarket 100 cell.
I think the prices might come down, but it will be sometime yet.

The GB on the H&S saved £100 ish over list?

Graham

 

Mark,I have got a 3" Milltek,Powerstation do a Milltek sport cat centre section for about £400 ish.I think they have used the centre section as the cat in the down pipe will restrict the spool up of the twin scroll turbo,(which I have got).I will try and get a gas test after it is fitted to make sure it is working ok.

Merv

£60 ish on the dp
£20 ish on the up
£30 ish on the long centre section

Mark

 

What about the Ninja sport cat downpipe from scoobyworld? Only £299.

 

Ninja is 2.5''?

 

Merv,
Do you know what size cat canister is being used?
I've thought of doing a cut n shut job on a downpipe, but have thought that a canister designed for a 2.5" system won't flow enough for a 3" system.
There is then the issue of whether a larger canister is going to foul the gearbox or bulkhead?

Nick

 

so the bellmouth version was introduced from '03 onwards?
must be honest i've only seen the split pipe version and there are a few people on ebay who try to flog the split pipe and are saying it's off an 04 or 05

cheers for the pics and info though

 

Soz for the hijack......

What is the purpose of the divider plate at the mouth of the cat?

Thanks
