I recommend purchasing the muffler of your choice, then go to a local muffler shop and have a custom setup welded in. This way, you can get any muffler you want, Flowmaster, Dynomax, Borla, Gibson, etc. You may come out cheaper this way too. Mine was $250 total, but I have 2 Flowmaster mufflers, dual pipes and chrome tips. A single setup should be $200 or less.
