give jm-garage a call, he seems to be good for zorsts.

that system looks fine, but tbh i\'d go for a full turbo back system

i\'m using their downpipe and de-cat. no probs so far. i believe adamfc is using one of them exhausts and a few others have used also.
they free-er flowing than stock and well made.

Is it for an EGi or a TII? Will be really stupidly loud on an egi, just very loud on a TII..

its TII and theres already an aftermarket downpipe on the engine. the shell its self is series 4 n/a. but have all series 5 TII bits goin into her. the shell had a brilliant series 4 engine wit also an aftermarket downpipe and decated and the noise of it was something else. Id take her for a quick spin down the road(few rings):driving and quickly back home cause not a stitch on her followed 10mins later by cops drivin up the road:2Confused never got me but had a few close calls but now she is sitting up in my shed getting a seroius amount of work done to her. hope to have it on the road by summer as hard to work on her wen im at college.

With 4" tips, thats going to be loud! The bigger the tips the more it acts like a megaphone!

What porting do you have on the turbo? my stock turbo boosted to 0.8bar on the 5psi spring boost due to not porting the turbo, crazy boost creap if the exhaust is made properly, mine was made at JM garage :)

4" tips yeah 103db @4.5k like mine! Not as loud as some though. A lot on single exits are as loud or louder TBH. Mine isn\'t too noisey when your moving either you can defo live with it, its the people your passing that can\'t!

Its perfect and almost the same as I had on my white cab. The noise is ok as well and the quality is also spot on. had mine on for two years and no probs whatsoever. quite a cheap exhaust for what they have been going for.

I was about to ask how bit liams kakimoto one was lol I can fit my whole fist in the end can lol

If you want a quieter exhaust get a Kakimoto red label, in japan, for there \'MOT\' there is a noise limit on cars, red label exhausts are MOT passable exhausts :)

im not sure if these are of the ssautochrome? My single exit one off ebay 3 inch all the way through to a 4 inch can is stupidly loud lol.

Ive seen this twin exit for sale which im quite tempted by but the peep\'s selling them say that the systems will fit a turbo2 and egi as they are the same??

I tried fitting a turbo two cat back to an egi and trust me they arn\'t the same as the y pipes are different lengths between the two car\'s.

Ive also heard lots of good things about jm garage too.

Just be careful if buying a turboback from the states, their WHD (wrong hand drive) cars don\'t need to avoid the steering rack in our RHD cars :)

Its nowhere near the stearing rack Mitch, mine was SSautochrome and came from the States. Thats really only FD\'s that have that problem.
