It has half the amount of cells inside it, therefore its less of a restriction.Normda, if you get a 4" dump, I'd get a 4" inlet/outlet cat (5" body maybe) and then you will have to figure out how to go from a single 4" to a twin 2.5" from there on. Maybe the exhaust shop can make up a y pipe to do that for you. Link to comment Share on other sites More sharing options...

Give Dom a ring, say Michael with the silver XR6 Turbo recommended him, and see if he gives you a good price. I always get my cars done there and so do all my family and friends.Haven't heard any good/bad feedback about Joondalup exhausts, sorry mate.

It is here My link at Xforce but it aint cheap, pic is the bottom left of all the clickable pics.Bit pricey at $1300 thou. Link to comment Share on other sites More sharing options...

They flow great and are quiet...I had a 3 inch high flow cat on my car and it was holding me back at 290rwkw..Put a Scottsrod one on and now I got 307 RWKW with just a replacement cat.....
