Ordering some test pipes and a y pipe to go with it soon bc mine is old rusted and the flex pipes are a little messed up, and I already have a y back exhaust so that will complete the exhaust. I was doing some research and saw a post about putting the HR y pipe on G35s, I was thinking that would probably be the best option since I was researching all different kinds of aftermarket y pipes and heard bad things about them and their flex pipes busting after a short time. Just wanting some opinions since all these posts were years ago.
Should I go with the hr y pipe or any suggestions for good quality aftermarket ones?
Also I was looking around and im not too familar with Zs, is there a certain years Y pipe i need to be shopping for? None of them I've seen specify it its HR or not.
thanks

 

Slow down, there's no reason to start swapping y-pipes from the Z or later models...stay with what came on your VQ motor in '06! Or you could go with an aftermarket y-pipe, either way I've never heard of them blowing up. Not a fan of test pipes, better idea is high flow cats which are legal in most every state except mine...damn Liberals!

my car is an 04 G. Just figured I would go ahead and do it since the old one is a little busted up and I'm replacing the cats. I was wanting high flow cats at first but I've found in other posts that test pipes offer more air flow/gains and a lot of the HFCs blow out after a while (mainly the Berks)
