Exhaust opinions with current tp
 

HI everyone I'm somewhat new to this forum and haven't really posted yet and just had a quick question to everyone.

i have a 2009 nissan 370z with stock exhaust except z1 motorsports test pipes that were installed recently. I'm in the market for a new exhaust and needing some opinions on what you guys think would sound good?

also for got to add that currently my test pipes are making a bad rattle sound and I've looked under the car when it was on a lift and even had a performance shop here check it out and they said it was fine but still continues the issue anyone know what this is??

Almost anything is going to get real loud with test pipes. I'm not sure if thats what you are looking for. Sound or performance?

I prefer the mellow tone to a car, otherwise a nice headache can ensue.

I would go Y-pipe, into a mid-pipe and retain the factory muffler or Y-pipe into the Stillen Catback which I have heard and is pretty mellow. But thats me, you may want everyone on the block looking at you like you are 18yrs old and driving a car with super powers, in which case you could go Y-pipe into AAM's mid pipe and run their Short tails. Basically a full straight pipe exhaust.

haha yes i am 18 but I'm not flashy about the vehicle. i drive it resposibly but other then that but I'm shooting for more performance with a tone that wont annoy me while daily driving. i find the test pipes i have currently to be a bit raspy

I like the way Litespeed Exhaust sounds with Z1 headers and TP. Try looking up some videos on youtube.

fast intentions.

It's a resonance characteristic of the motor -- probably sounds real bad on coast down around 2K RPM...

Are the TP's resonated? If not, I'd swap in a set for less rasp.

Other than that, you will hear some rasp with any set-up -- it might be a bit less if you switch from a Y to a H-pipe as the H equalizes the pressure waves coming from each bank and helps neutralize the harsh resonance.
