What is a good ypipe that would give good gains with the RSR exhaust? Also, what high flow cats are the best to get? I've seen a lot of posts lately about the RT cats blowing up i think. Give me some opinions/ideas!

 

I have a couple thousand miles on my R/T cats and so for they are working out great.

 

if emmisions arnt badin yer area just get test pipes...alot cheaper and a lil bit more power

 

ultimate racing, crawford, and labree are the only cats i know of that i haven't read any complaints about

 

I'm pretty sure i can get past the emissions stuff. I just dont want the cats blowing up or anything. Not positive i'm going to get them, but i was thinking about it and figured i'd check what you guys thought. Mainly really interested in finding a good YPIPE

 

Check out the Gruppe-S Y-pipe. It's an exact replica of the Fujitsubo Y-pipe and it's only $275 shipped.

I installed one of these a few days ago and it is a really nice piece. Fits perfect, includes all hardware, perfect welds and a beautiful polished finish (a shame it goes under the car )

 

Notice any power increases with the new y-pipe?

 

a ypipe should give you 4-6hp or something around there.
some out there claim an 11hp increase, but i think that is exaggerated.

 

FairladyZ: Hard to tell. It's been just a little over a week, but I honestly can't feel much difference at all. Than again, I only have the Y-pipe and a 350Z intake tube on my G35C, so YMMV. I'm planning on adding a Y-pipe back exhaust soon.
