This exhaust gave me the note that I have been looking for and was fairly painless to install

Best bang for your buck

Love the sound and the look but it has a little bit of a fitment issue where the left side was a little closer to the bumper then it should but it's a simple fix by bending the exhaust hangers. Easy removal and installation. All the gaskets and bolts are provided and well needed. In the end I love it, love the sound and the price.

Great once modified.

This exhaust became ideal once a mufflershop did proper adjustements ($250) to make is sit perfectly flushed in the fender like the stock exhaust. Sound is gloriously sonorous.


Sounds great, zero rasp or rattles. It has a very deep tone and rumble and for the price I can't find anything to nitpick.

Great Exhaust!!!

I bought this exhaust to go with my Tsudo catless DP and it sounds amazing! It is just a tad bit louder than stock when cruising but really comes alive when you put your foot down on the gas.
