Walker Exhaust Exhaust Muffler Assembly P/N:46748

Quiet down a loud, raspy exhaust and get factory-style sound back with the Walker Quiet-Flow Direct-Fit Exhaust Muffler Assembly 46748. The manufacturer catalogs it as a direct-fit, bolt-on replacement for the BMW 325i, and it drops in with factory-style mounting hardware so no specialized fabrication or welding is required. A muffler dampens the pulses of exhaust gas leaving the engine to lower noise — if a rusted-through, rattling, or blown muffler is behind your loud exhaust, this replaces it.

• Direct-fit, bolt-on: ships with OE-style pipe routings, brackets, and hangers for an easy swap that skips custom fabrication or welding.
• Premium acoustic control: OE-style louvered tubes and domed heads help lower and reduce radiated noise for OE-style sound quality versus straight perforated tubes.
• Built to last: internal partitions and mechanically joined tubes allow expansion and contraction with temperature changes, while spun-locked heads and OE-style spot welds add stability.
• Resists corrosion: an internal drainage system helps reduce moisture collection.

Construction: aluminized steel, oval body, with a 2.25" outlet (OD), dual tips, dual inlet/outlet, and a 2-bolt loose flange inlet. No gasket or seal is included — consult the vehicle service information for the correct hardware and whether it may be reused. Backed by Walker's limited lifetime warranty and 90-Day Safe and Sound Guarantee. Country of origin: Taiwan.
