You will get more boost and if the turbo has not been ported etc it will spike its tits off...I have the xforce split dump into single 3.5in stainless system, the cat has been replaced with a piece of stainless pipe with flanges to bolt in/out if needed (but haven't), my rear muffler is different though as my system was bought back in 07-08 when they had the twin exit that was restricted so I use a single small generic muffler which is 3.5in in and out.The cat removal is def worth the little dollars but a tune will be required along with those turbo mods which my car has not had so boost is high at 18-19psi but power has been deliberately brought down to keep the engine together.Go the varex also as they do work and as afaik they dont cause issues when cruising with it shut in silent mode. 1 Link to comment Share on other sites More sharing options...

Yeah I got internal gate welded with a external wastegate & screamer and eboost 2 to monitor the boost .. Got a boost cut in Aswell so should be pretty sweet .. Do u get any flames or popping from it ?? Edited 02/10/12 06:30 AM by IMLOCO Link to comment Share on other sites More sharing options...

I don't see how a free flowing exhaust could make matters worse.I just didn't want to spend that coin and don't want a loud droney exhaust as a result..

Lag is most likely related to my wastegate flapper and actuator being faulty.. Link to comment Share on other sites More sharing options...
