A friend of mine has a 97' GXE Maxima 5 speed. He wants to get an aftermarket y-pipe. I usually help him out when it comes to mods. I was wondering which Y-pipe would give the Maxima the most performance out of the Stillen or the Cattman.

Another Question: What catback system works best for the maxima? Also, which headers are work best for the maxima?
As far as intakes go, Place Racing is the way to go. (Correct me if I'm wrong.)

For now, all he has is an exhaust pipe. At the track, he's ran a best of 15.5 sec at 89 MPH. He's trying to get his time down to run low 15's easily or high 14's with a good driver on mods like the ones I mentioned.

I would appreciate it also if you have prices for the Place Racing Intake, Stillen and Cattman Y-Pipes, and headers.

Peace!
