exhausting work

[blurtmagnet]

my down pipe snapped at the turbo last week so i thorght it is about time for a full new system from the turbo back with a screamer pipe.

i rang Longlife exhaust in leeds and they told me i had to take the car to a turbo specalist to have the turbo removed to be able to replace the down pipe on an S2 3B

i took it to topgear performance in Doncaster and they recomended a 2.5" down pipe and if i wanted to go 3" it should be after the cat's. they said it wouldnt make much difference to the performance?
also while the car was up on the ramps we couldnt see a big enough gap for the screamer to exit the engine bay (RS2 EM, stock position). so we came to the conclusion that a 2.5" straight through with the wastegate plumbed in further down the down pipe would be the best choice.

i know other people run screamers and have 3" turbo back zorst's, does anyone have any pics of their screamers so i can have a look? and why would both places advise me like this?

Because making a 3" downpipe is much harder and they either havn't got the skills or can't be arsed to do it. Do some searching on here and you'll soon learn that a 3" downpipe is worth having.

As Andy has said people are getting lazzy when it comes to work like this, My self and a few other forum members are using a 4" down pipe with big turbos they do fit but its taf!


Ditch the cats as well

[blurtmagnet]

cats where removed when the scorpion exhaust was fitted to the car before i owned it. and it looks soooo restrictive. the pipe to the back box is all sorts of shapes and the swings round on a 90degree angle to come out on the passengers side.
i have read allsorts on this. they are going to put the box before the axle and then the pipe exit on the drivers side. as straight as possable..
so i'm being took for a ride because they cant be arsed? ......
what about the comment from Longlife? is that just being lazy aswell?

Sounds that way, if some have 4" and loads of us have 3" downpipes (myself included).

If it's fabricating a 3" downpipe that they don't want to do, I think you can buy just that section from the 034 website (but it will have a stock entry for the wastegate).

034 20v DP

Good exchange rate, just hope it doesn't get held up.

[blurtmagnet]

thanks guys.
any news or pics regarding the screamer?

This is the place MRC use.

Only thing with the 034 DP is it uses a 2.5 to 3" taper which is alright for the KKK turbos but the Garrett turbos have a 3" 4 bolt exit so there's no need for the taper.

I happen to have a full 3" stainless system from 034 for sale. It only has about 1000kms on it. Comes with a Borla rear muffler, optional high flow race cat & V-bands. I'm asking $850 CDN for it plus shipping. It's the shipping that would be the kicker though.

i'm going to take out the y peice and remove the cats, and have the exhaust pipe as straight as possable. having just one silencer in front of the rear axel so i dont have to have a box hiding under my bumper with so many bends in it.
i would take the down pipe off your hands tho.

@ Jamo,
thanks for the link, i'll give them a bell in the morning and see what there prices are like. my wallet isnt as heavy as some peoples on this forum lol

the guy at topgear wants to use the cast part from my old down pipe and weld it to s/s so he can keep the flange. any thoughts?
anyone know the size of the cold side of a K26/K27 turbo
i take it 2.5 is too small for around 300-350bhp?

The RS2 downpipe is 2.75"

[Greg_S]

See here details of the exhaust I had made a while back.

Dont use prism motorsport though

I have the 034 3" downpipe on my ABY, connected to the Garret GT3071R with K26 flange and the Wagner RS2 HO Cast EM, but I can tell you that the downpipe hits the subframe permenatly. I had to modify my subframe and the downpipe to make it fit.

It seems the 034 3" DP is better designed for the UrS4 then the S2. The same counts for the 2,75" inlet hose on the Garret from 034 motorsport. I had to make a work around to fit the WGFV and DV.

try corey

i know he's had a lot of bad press lately but the system he did for me is of top notch build quality. he didn't make it but it was easier to get the turbo swapped instead of fannying about dragging the car here n there.
