Single Exhaust Vs. Dual
 

Whats up peoples. I have a question for you all. Whats the advantage for single exhaust with the Z compared to dual exhaust for the Z?

Single path and dual path are only 2 variables to look at. Pipe diameter, material, flange/clamp, and bends are other factors. Sure, it "sounds cool" to tell your friends that you have a "dual exhaust", but does it help or hurt performance. On a naturally aspirted car a larger diameter exhaust can and will reduce performance. A PROPERLY designed system however can yield nice gains (see Motordyne). This is a very in-depth topic, research online.

go triple!

or no exhaust! LOL
