The MagnaFlow XL 4x9in oval multi-chamber muffler (model 13236) pairs a perforated stainless core with baffles and tuning gates to control resonance while improving exhaust flow and producing a strong signature tone. The reversible 2.5in offset/offset inlet layout and 4x14x9 satin-finish body support varied installation requirements. CNC precision stainless construction and a limited lifetime warranty back the design.
