Designed for vehicles racing at venues requiring a muffler, but can be used on other applications. Reversible design for installation flexibility. Patented Multicore design for maximum power. Recommend for high horsepower applications. T-304 Stainless steel will never rust. 100% welded construction for strength. High-temperature continuous-filament fiber (CFF) acoustic material 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.
