MagnaFlow Muffler Trb SS 4X9 18 2.5/2.5

MagnaFlow XL Mufflers use a unique combination of large diameter perforated tubing and strategically placed sound baffles to reduce unwanted resonance and help your engine create horsepower. The sound baffles tune the sound waves using calibrated tuning gate openings that allow portions of the waves to pass through. These tuned waves reflect off the back wall of the muffler and cancel out unwanted harsher sounds. The large diameter perforated core eliminates the flow restrictions of a louvered style core. A careful balance between perforation size/spacing and the baffle tuning gate make for a great 3 chamber performance muffler.This Part Fits: Year Make Model Submodel 1988-1993 Chevrolet C1500 Cheyenne 1988-1992 Chevrolet C1500 Scottsdale 1988-1993 Chevrolet C1500 Silverado 1990-1993 Chevrolet C1500 WT 1988-1993 Chevrolet C2500 Cheyenne 1988-1992 Chevrolet C2500 Scottsdale 1988-1993 Chevrolet C2500 Silverado 1988-1993 Chevrolet K1500 Cheyenne 1988-1992 Chevrolet K1500 Scottsdale 1988-1993 Chevrolet K1500 Silverado 1991 Chevrolet K1500 Sport 1990-1993 Chevrolet K1500 WT 1988-1993 Chevrolet K2500 Cheyenne 1988-1992 Chevrolet K2500 Scottsdale 1988-1993 Chevrolet K2500 Silverado 1988-1993 GMC C1500 Sierra 1988-1993 GMC C1500 Sierra SLE 1988-1993 GMC C1500 Sierra SLX 1988-1993 GMC C2500 Sierra 1988-1993 GMC C2500 Sierra SLE 1988-1993 GMC C2500 Sierra SLX 1988-1993 GMC K1500 Sierra 1988-1993 GMC K1500 Sierra SLE 1988-1993 GMC K1500 Sierra SLX 1993 GMC K1500 Sierra Sport 1988-1993 GMC K2500 Sierra 1988-1993 GMC K2500 Sierra SLE 1988-1993 GMC K2500 Sierra SLX
