IMLOCO Member 397 Member For: 12y 11m 20d Posted 01/07/12 11:42 AM Share Posted 01/07/12 11:42 AM Hey guys !! I've got myself a ba mk2 xr6t ute and it's got a cat back system on it ... Fairly sure it's a 2.5 inch system ... Now I'm going to be aiming for around 400hp down the track ... Would I be able to utilize this system it has on it already an just add a dump pipe and cat combo or should I completely forget It and go bigger and better ? Also if I was to keep the cat back system that's on it now if I added a new dump and cat what would be the best to run ? Split dump or 3.5 inch or 4 inch ? Thanks in advance Link to comment Share on other sites More sharing options...

I think I might just do a full turbo back system ... Would a single 3.5 inch system and 4" dump be enough and not restrict it ? And a good cat of course Link to comment Share on other sites More sharing options...
