I just came back from a test run with the MBRP muffler kit installed (MK96116). I'm loving it. Just a little louder and throatier than stock. Took about 2-3 hrs. to install. I did have to hack off about 7 inches of the rear section of pipe. The kit must be a little longer than the stock muffler. If you want better exhaust flow with a little more noise this kit is it. Now I just have to get some gauges.

 

I love this muffler too, Now i'm wondering how it sounds when the dogs chases the cat away.
