TRINITY RACING Muffler - Black TR-4176S-BK

A quality muffler doesn't just reduce noise—it eliminates backpressure that costs you horsepower and throttle response. The TRINITY RACING TR-4176S-BK is engineered with a 2.5-inch baffle and 304 stainless steel construction to deliver measurable performance gains while maintaining street-legal sound levels. If you're serious about extracting every bit of power from your engine, this is the exhaust component that actually delivers.

Built entirely in the USA with TIG-welded construction and precision 6061 billet components, this muffler handles the demands of both track and street driving. The included quiet core gives you flexibility to dial in your desired sound signature without sacrificing flow characteristics.
