Ok, I bought my Z about 3 months ago and I'm getting ready to buy an intake and exhaust. When it comes to an exhaust system whats best, Y pipe or true dual? and how big can i safely go (3" pipping)? Also, what other mods can i do to the engine keeping it NA? Thanks for your help and time.

 

Dang n00b. Nobody, espeically in this forum, are going to want to answer this. Go spend some hours reading threads in this forum:

Then formulate your own educated opinion of what is best.
