Has anyone installed one of their cat-back systems?
If so, how does it sound?
Was it easy to install?

 

installed a cat back on my 01. It was very easy to install and has a nice sound not very loud. seems to be good quality for the price.

 

Thanks Dominic. Looking at the pics on their website of the SISO, it looks easy to install with all the hangers welded in place. Is their muffler a straight through design or is it chambered? Do you get any drone inside the cab at any rpm's?
