DynoTech long tubes with their free flow cats and Y Pipe a little pricy. But. My muffler went on with out a problem. Oh and worth every penny same headers have been under my hood for 10 years and on two 5.3L's and three 6.0Ls engines.
Kooks are good too. Shortys don't do anything for these LS motors unless they are flipped unside down to a turbo!
