Just wanted to put a video sound clip of Borla on a single turbo with a stainless custom reverse Y pipe. Wasn't enough room to wot but here's 1/2 to 3/4 throttle. It is real quiet. To quiet for me, tomorrow morning I am having the resonators removed will post another video and a pic of the exhaust when its up on the lift. Listen to that loud azz JWT flywheel at the end, when I had my procharger and tp's I never heard it.Another reason to cut them off is to get more flow.

 

you need a 3" exhaust youre losing power with that 2.5"

 

Before the resonators are cut off.
