|---|---|---|---|
EASY TO INSTALLDirect-fit bolt-on replacement includes OE-style hangers, brackets and pipe routings for easy installation and doesn’t require specialized fabrication and/or welding |
CORROSION RESISTANT STAINLESS STEELThe only broad-market muffler with 100% stainless-steel construction that delivers longer life versus aluminized mufflers while an internal drainage system reduces moisture collection |
PREMIUM ACOUSTIC CONTROLOE-style louvered tubes lower noise levels while OE-style domed heads help reduce radiated noise for premium factory-style sound quality compared to straight perforated tubes |
BUILT TO LASTInternal partitions and mechanically joined tubes allow expansion and contraction during temperature changes to minimize distortion while spun-locked heads and OE-style spot welds provide structural stability and longer service life |
WHAT IS AN EXHAUST SYSTEM?
Vital for fuel economy and the environment, your vehicle’s exhaust system carries away harmful gases that are created during the combustion process. The exhaust system not only keeps dangerous gases like carbon monoxide, nitrogen oxides and hydrocarbons from entering the cabin but it also "cleans up" the gases before they are released into the environment. Here are the components of an exhaust system:
- Manifold/Manifold Converters
- Oxygen (O2) Sensor Ports
- Catalytic Converters
- Resonator Assemblies
- Mufflers/Muffler Assemblies

|---|---|---|---|
SIGNS OF MUFFLER WEARMufflers primarily deteriorate from the inside out due to the acidic moisture produced by the combustion process. Other signs you may need to replace your muffler include noise coming from the muffler, a foul odor from not properly filtering exhaust gases or a distorted body shell. |
HOW TO TORQUE FLANGESProgressively tighten bolts on flanges to avoid exhaust system leaks, gasket & stud failure and premature system fatigue & failure. For example, if the nuts require 60-ft-lbs of torque, start by torquing all nuts to 20-ft-lbs, then 40-ft-lbs and finish at 60-ft-lbs. For Y-pipes secure both sides simultaneously, tightening in a rotating sequence between both pipes. For manifold converters, begin sequence in the middle & work evenly out between both sides. |
CHOOSING THE RIGHT CLAMPManufactured from premium steel, these clamps are available in multiple varieties of saddle, band and wire ring clamps. Selecting the correct clamp style is critical for achieving desired levels of sealability, durability and serviceability. May require separate purchase. |
WHY MUFFLER QUALITY MATTERS?A muffler’s cross section is key to its performance. Walker Quiet-Flow SS mufflers feature OE-style cross sections to deliver the same quiet, factory sound experienced when the vehicle was new. Walker’s approach helps prevent degraded cabin acoustics, including exhaust drone. |

Perfect fit and replacement for OEM muffler on Jeep
The original muffler on my 1999 Wrangler was finally going bad.( 1st picture) This item was a perfect fit. I had to cut the old exhaust just forward of the muffler since it was the original and would not come apart. Bought an adapter at the local auto parts store (2 1/8" ID to 2 1/8" OD) to join the muffler inlet with the pipe from the catalytic converter(2nd picture). Test drove it and had to retighten the clamps, but Jeep is much quieter,
