I have a Flashpaq, a throttle body spacer and an XDI intake all which I am happy with over all. Anyone have an after market exhaust only and how do you like it? Anyone install one with a similar set of engine mods and how did it perform? On any application from pickups to my old track mounted drill rig, exhaust has always shown improvement however Ive never seen high ratings for improvement on this forum. Any thoughts?

 

MBRP exhaust. Like it so far. At least lets me know I have an engine under the hood.
