Message: I am looking to change my muffler on my 03 3.9 6cyl Club Cab. I wanted something that sounds better than the stock exhaust but, not something that is obnoxious loud. Flowmaster, Dynomax ??? I live on Long Island, NY if anyone knows any good muffler shops. Also maybe something that increases perfomance. Please help. Is meineke any good they sell their own brand.
