Rcm UEL been on mine for a few years now no problems

Ooops just jinxed that now

 

You obviously don't drive it hard enough to exceed the heat range of 304 stainless.

If you were it would have gone brittle and cracked by now

 

Lol, tbh it had been out of action for quite a while due to the recent makeover so that has probably helped

Track day on Monday (first one for a while) so I'll try then !!

 

Good luck!

Mine would last a year to 18mths max.....

 

 

That seems excessive, although you probably get to the strip/track more than me, what egt' are you getting? Last track day I did mine got to 900 from memory

What make banny?

 

They look good.

Are the wastegate on the manifold or up pipe? It looks like they are on the manifold?

 

Custom made for Pat at scoobyclinic to his spec

Correct wastegates are on the manifold itself, had to shorten the take offs a little as they were quite close to the wheel. Thought the position of the gates may cause an issue with them opening prematurely ane need moving up slightly on the manifold, but since repiping the gates correctly they have performed perfectly

 

It's pretty poor that they weren't piped up right to begin with and no one picked it up!

I run ewg on my starlet and the noise drives me up the wall I wish I'd piped it back into the down pipe.

IainMilford, I don't know what my egt was I don't measure it. But I use launch control etc a lot so fairly high I imagine

 

Yep very disappointed J but I did lose interest in the car, so I am partly to blame for taking so long to look into it. All is well now though and I agree not a big fan of the screamer noise much prefer the natural exhaust note, but it would be too much pipework to even attempt to pipe them into the dp

 

Well I have been away for a few days / week and seems I have opened a very debated topic it seems. Has been very interestING to read everyone's input.
I think based on the fact I am looking at majority of the car running standard with a few basic minor mods I'll be putting the standard UEL on replacing the toyosport EL. I'm not after monster 500bhp nor looking to spend much if anything (save a remap) and so the minor difference's it will make at my level will be outweighed by that boxer rumble I fell in love with as a kid and made me want a scooby ever since.

I appreciate everyone's input and always love how a forum can bring so much help and mixed opinion. Good work

 

You Tommy, you took the jam out of my doughnut

 

I own an Evo and Scoob.

I bought the scoob for the rumble. Thats all!

The Scooby is a daily driver, there is no need for me to push it to extremes of power and get every oz of it when it is running around 340bhp. I am happy with the drive. Its a road car.

If it was a track car, I would squeeze every oz of power out of it for the performance edge. On the road no one is going to notice the difference of equal vs unequal due to road restrictions.

just my 2c

 

But that is your 2c with no personal experience. Based on opinion only.

As has already been mentioned in the thread, you will certainly notice the difference even at 300hp. And on the road drivability is king and uel drive worse than el....

 

My evo is 550bhp twin scroll with a so I do know the difference. The scooby is perfectly drivable on the road. Unless you are planning to use the road as a race track? Even taking another car off the lights, the difference in acceleration is marginal, particularly as people need to consider the human factor too

 

The difference between uel and el is night and day. Not forgetting that fact that there is a significant power gains to be had....

It might be drivable, but the lag is worse, transient response is slower, and you have less midrange torque.... hey its your car, but I know I'd rather have the benefits from a properly designed manifold, no down sides and plenty of pluses.

Infact I'd say at a lower power level you would want it more responsive. Why have 340hp for it to drive like 500?

And how does a 550hp evo drive anything like a subaru? How many uel evo have you driven?

 

Problem is most folk dont fit a £2k killer bee manifold to a 340bhp Scoob.

Are there any more affordable headers which live up to your high expectations J. As in ones which dont cost the same as a good turbo upgrade ?

I would like to see the difference between rcm uel and el ?
On same turbo.

If i paid 2k for any car part and didnt notice good gains or something better id be pissed. So no shocks that killer bee changes your car.

 

Its not just me who noticed the benefits, as can be seen on this thread....

Youre wanting to compare like for like, so comparing a 550hp twinscroll evo to a UEL 340hp subaru is ridiculous.....

I dont know,, I wouldnt fit anything made out of 304 stainless to my car ever again, it is cheap shonky crap IMO. Whether it be RCM or anything else it is still ****e no matter hwo good the performance gains are when you have to keep replacing them!

The manifolds are not that expensive when you factor in having to replace the RCM ones a couple of times, life time warranty will soon pay for its self...

 

Even stock then.

Has anyone bothered to go from stock uel to stock el ?
On same turbo ??

 

There is no such thing as stock EL turbo manifolds....

 

Ok so killer bee or dont bother ?

 

That's the reason I bought the HKS equal lengths as they are a lot better value for money, read some good reviews across the water and several have had them on for 30k plus with no issues. I know they are made of inferior metal to the killer bees.

But I have seen a couple of posts of the killer bee up pipes splitting. I know they have a lifetime warranty but if there is any issues you will not be sending them back to America

 

Did you just do the manifold as a single mod on its own ?
How were the gains ?

 

yes single mod, being mapped on Saturday morning at EngineTuner so will see any gains then. Car is already smoother without map

 

They should last better than the rcm ones that's for sure. I wouldn't say they are a lot better value for money though. I'm happy with never needing to spend out for a set of manifolds again....

However of course I'd be getting a replacement up pipe from America should anything happen. It's all part of the deal. And of course you'd send it back, it has no value broken and wont be taxed etc that's a bit of a bizarre statement to make....

 

So killer bee or dont bother would you say ?

 

Its still going to cost you money to post back to America. You will be without a manifold for several weeks by the time you return it and they send another one out

 

The Killer Bees do look the b#locks. How long you had them on the car

 

Wouldn't cost me a penny it is all covered under warranty.... and whether I am without a manifold for a week isn't a big deal. Of you are spending that kind of money on it it's not a daily driver...

Had then on a few years now....

 

Anyone used the full race headers
