This is the HOT set up in drag racing. This patented, award and race-winning product was designed to replace your current open header collector and serves as a power producing merge collector and muffler -- all in a single unit. Made with the same patented, award and race winning flow through design as the Standard XR-1? Collector/Muffler. This muffler, however, is designed for door car applications where a Standard size Collector/Muffler is too large. This muffler is recommended for Full Chassied Cars. Accepted in NHRA, IHRA, Hot Rod Series, Brackets, Super Chevy, and NSCA. Recommend for high horsepower applications. T-304 Stainless steel will never rust. 100% welded construction for strength. T-304 stainless steel wool for sound control. Best of all, it's made in the USA. Just what you'd expect from the world?s most experienced (and most winning) exhaust brand.
