Ok guys, I need your help. I posted in the 4th gen section, but unfortunately no responses! I am getting ready to purchase a stage 1 ACT clutch kit, lightened flywheel, and I also want to get a 2.5" exhuast. My main concern, besides quality, is sound. I want to have the nice rich sound but not an annoying idle hum. I'm hoping to make it as close to a 350Z as possible. I have been seriously considering the warpspeed 2.5" complete exhaust for $599, but how does it sound. The kind of note I like is something like the 350Z, or as similar to an M3 E36 as possible. Nice, deep, mean, but not ricey! Please, any suggestions? Thanks, Alex
