I love the MBRP stuff, but that's way out of the budget for my truck. The truck has been my work beast since new (198,000 miles now), so not planning on spending too much $$ on performance stuff, just replacement. I'll check into the Thrush. I had forgot about them.
Too many other toys around. I have a GMMG cat back chambered exhaust on my 99Z28 and have loved it since day one. I don't anticipate putting any kind of exhaust on the CSRT4, as There's just no good way to make a 4 cyl sound good to me.
