Designed for rotary engine equipped vehicles, but can be used on other applications. Compact design is perfect for applications with limited space. 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 (CRF) acoustic material for sound control. There is no logo embossment on this part. 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.
