MagnaFlow XL 3 Chamber 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. The large diameter perforated core eliminates the flow restrictions of a louvered style core.
I have a question about this muffler (part #13148) can it be used as dual inlet, single outlet as apposed to single inlet dual outlet? The magnaflow website says it is reversible but im just making sure, will be going on a 1998 GMC Sierra K1500 5.7 4x4
