Has anyone put a thrush turbo muffler on a 2006 2.4 LT? I will be putting one on in a few days. I was just wondering how they sound,(I Did youtube them), if they increase HP & fuel econ.
Just wondering. I Already have the muffler, Intend to put it on, but was curious if anyone else tried the same.:nuts:
