Flowmaster 2.5 IN(O)/OUT(C) Super 40 SS Muffler

The Super 40 has that deep powerful sound of the Original 40 series but with all the benefits of performance and low interior resonance from the Delta Flow® technology. Constructed of 16 gauge 409S stainless steel and fully MIG welded for maximum durability.
