EMPI Phat Boy Muffler for Merged Header- Stainless Steel
Phat Boy mufflers have a distinctive growl, making your engine sound and run fantastic. They make great horsepower, too. This design is to me used with our MERGED header system (#3699, #55-3699, #7320, #55-7320). Available in black painted, ceramic coated, or stainless steel.
