- Walker® Quiet-Flow SS Muffler features a 100% stainless steel construction
- Precision fit, superior flow and OE-style sound and performance
- Fits like OE because Walker makes OE
- Spun-locked heads help resist ruptures due to backfires
- Durable internal partitions for greater interior structural stability and a long service life
- Strong, OE-style spot welds help improve structural stability and increase durability
- OE-style louvered tube technology lowers the engine emissions noise level for a premium, OE-style sound
- OE-style domed heads help reduce radiated noise
- A complete internal drainage system helps prevent condensate acids from collecting between partitions or at the muffler heads
- Internal tubes are mechanically joined to the partition to allow expansion and contraction during temperature changes; this special design helps eliminate the breaking of spot welds and subsequent part distortion or loose part noise problems
