just in the market for b pipes..and was wondering how much they go for..and who makes them..for my car..etc etc..give me some info if u got some..thanks..

 

So far Courtesy Nissan and Stillen are the only makers I know of. I recommend you changing the y-pipe and intake first. I think you should start at the beginning of system. The B-pipe is just about last...next to the muffler. I just received mine today and am planning on installing it tomorrow. It just turns out that my maxima has the third O2 sensor after the cat, so the courtesy is a diret bolt on.

 

u should get a ypipe instead bpipe cost alot and gains not as much as ypipe though its for offroad. everyone has it

b-pipe about 160 to 180 7to9HP?

y pipe 350 to 400 15HP
