I talked to a place in washington and they quoted me a good price on a cat back.has anyone here have any experience with these
thanks Richard

 

haven't tried it but, I had Thorley headers on my Ram 5.9L. Other than turning color, they were a sweet set of headers. I've since sold the truck which was 12 yrs old. I just saw it the other day cause the guy had some questions and the headers still look to be in outstanding condition.

This doesn't help about a cat back system but, I can vouch for Thorley's quality
