I'm trying to find out about the motordyne exhaust I'm gonna buy. Now my question is I'm doing a twin turbo 350z and the shockwave tdx is for a turbo application. Now I want to go full 3" but the only problem I see is the art pipes are 2.5" and I hope the are for a turbo app. But how to I connect a 2.5" to a 3"?

 

You won't use ART pipes with a turbo kit, the down pipes will connect to the exhaust.

 

The art pipes are down pipes

 

Okay.
