Gibson Exhaust 789800S GIB789800S SFT SUPERFLOW CENTER/DUAL ROUND MUFFLER, STAINLESS

High Performance Universal Superflow SFT Mufflers delivers the powerful "big block" sound at the tailpipe with more usable pulling power and torque! The Gibson difference is that our mufflers are quieter inside the cab than any other aftermarket muffler. By baffling and chambering our Superflow SFT Mufflers, (not packed or screened, nothing to blow out) we promote better volume efficiency with unrestricted flow. Plus, the added thickness of the muffler case and heavy duty tubing, all contribute to keeping the noise inside the system. Recommended for big block motors with catalytic converters. 6", 7" ,8" round diameter.
