Did require my tailpipe to be cut despite the service rep telling me it wouldn't

First thing I noticed was the sound and then the response I felt when I hit the gas... I'm extremely satisfied with my purchase of the system. The one thing I would suggest is that MBRP includes the clamp that attaches from the catalytic converter, all other clamps are included but had to do some serious tweaking to use the original.

After tons of research on forums, auto aftermarket sites, and even calling the manufacture directly; I finally decided on the mild tone muffler (I couldn't find any reviews on this model). I have to say I am very satisfied with my decision. The sound is noticeable but not overbearing at all. Nice deep tone. Love the straight through design. I feel that it improved performance with a 3" cat back. Highly recommend.
