I installed an Dynomax Super Turbo on my '04, mimicked the size and shape and like the result. It was only slightly louder than stock with the desired performance gains. I want to go SS this time around and do basically the same thing (size and shape) and am considering this muffler. I searched and seems like most who have these are running 2. Anyone have 1 w/SISO?

 

Junk chambered design. Want performance and quiet go with the 22" body.

 

A little more clarification. Any one in particular on off this page?
