Flowmaster introduces its new Slimline sidepipe style mufflers. Part # 13524320 has an inlet and outlet diameter of 3.5” with a 4.5” body and 24” long case. Part # 13530320 has an inlet and outlet diameter is 3.5” with a 4.5” body and 30” long case.
Intended for Shelby Cobra and Corvette sidepipe applications, these Laminar Flow technology mufflers can be used in other applications and feature a raw 304S stainless steel case with no logos for a cleaner appearance. These mufflers offer a quieter alternative to the glasspack style mufflers that are traditionally used in these applications, with still a moderate overall sound. The Cool Shell Technology helps prevent the outside of the muffler case from seeing the extreme temperatures associated with sidepipe applications. The Slimline mufflers are made in the USA and backed by Flowmaster's Lifetime Limited Warranty.
