All Black Widow Exhaust mufflers are universal and can run bi-directionally (either way) and will not affect sound quality. For optimal sound and performance on dual exhaust systems, we recommend a crossover pipe (X or H pipe). Installation may require additional materials such as tubing and adapters. Because of this, we always recommend installation by a qualified muffler shop.

Factory mufflers install with at least 1 (sometime more) hangers directly connected to the body of the muffler. Our Warranty requires the same. Please see our installation card below.
