Could someone go over the effects that an exhaust upgrade would have on the way the car performs and sounds? Some numbers for the performance, and perhaps an .mp3 or a video for the sound would be great! Also, what's the range, for parts only, and what do most people prefer to upgrade to?

 

you ever heard of the search function on this forum its pretty useful. There is like a whole thread dedicated to exhaust sounds.

 

louder..not much faster..

 

Well, it's just the thing to do.

But use the search.

 

Not much performance really .... different sound all depends on which exhaust though. Other than that look at the sticky about exhausts or search.

 

Use can check dyno charts of a 350Z similar to what you are considering. You can also review quarter mile time slips.

I believe that the entire OEM exhaust from the engine back should be replaced. Perhaps not all at once, but as a long term goal. Exhaust components are tricky because they change both the torque and horsepower curves. Its possible to add peak horsepower, but sacrifice low end torque. After intake and exhaust mods are completed, a tune up is a must.

 

* Performance: gain few hp. let say about 8 to 15hp
* Sound: Louder than stock
