Q: What other products would i need to install this on my 2005 Silverado 1500 5.3l? Leaving the rest of the exhaust stock, and also can I just cut the stock muffler off and clamp this one on, or does it have to be welded? Answer this question

A: Tucker- Thanks for asking. Flowmaster does not make an exact replacement muffler for your 2005 Chevy Silverado 1500 with the 5.3L V8. It will require a muffler shop to fabricate piping to install this. I would recommend the Flowmaster cat back systems to get the best performance for your money. You can find them here
