New 3.0" Stainless catback now availible. Includes all stainless siamese design X pipe, 1 piece slip fit tailpipes, Pypes Street Pro mufflers, stainless band clamps, hangers, hanger insulators and polished stainless classic double box tips. No cutting or welding required! Increases horsepower by 10-18. Street Pro adds the famous chambered sound at Idle and cruising but doesn't get obnoxious at full throttle. Also SEE SMC21R or SMC21V.
Street Pro: This is a great street/strip muffler that will maintain its rich sound qualities for the life of the muffler because there is no filler to burn off. Recommended for stock to medium modified vehicles where an aggressive sound is appreciated but not advertised. Sound Rating = [7.0/10]
Note: Use SMC20S for Auto trans models.
