w/ Quiet-Flow Stainless Steel Muffler

Walker Quiet-Flow Mufflers feature 100% Structural Stainless Steel construction to resist rust-out three times longer than competitors' premium aluminized mufflers. Bolt-on replacement solution with OE-style hangers, brackets and pipe routing make installation easy (no welding or custom fabrication required)!

Features & Benefits:

1
Spun-Locked Heads help resist ruptures due to backfires.
2
Bridge Construction for structural strength and a long service life.
3
Durable Internal Partitions for greater interior structural stability and a long service life.
4
Strong OE-Style Interior Spot Welds help improve structural stability and increase durability.
5
OE-Style Louvered Tube Technology lowers the engine emissions noise level for a premium, OE-style sound.
6
OE-Style Domed Heads help reduce radiated noise.
7
Complete Internal Drainage System helps prevent condensate acids from collecting between partitions or at the muffler heads.
8
Internal Tubes are mechanically joined to the free-floating 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.

Benefits of Purchasing an Exhaust System Kit

Replacing just a section of your exhaust system is less expensive up-front, but a complete Exhaust System Kit provides added benefits:

  • Extend Service Life: New clamps, gaskets and hangers (where applicable) prevent exhaust system leaks or damage that can occur when reusing old / incompatible hardware.
  • Reduce Install Time: All included parts are guaranteed to fit together seamlessly to ensure a smooth, problem-free installation.
  • Save Money: The cost of the complete kit is often less expensive than buying the components individually, and means you only have to do the job once.
