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. |

Great muffler with my SuperCharger
I installed this muffler on my 2001 4Runner and it fit like OEM hardware without any modification to the original equipment. The muffler alone does not include gaskets, bolts, or rubber insulators. There is a write up on ToyotaOff-Road.com that has full install information and pics that makes installing this muffler extremely easy.This muffler is dead quiet on my 4Runner and it is even supercharged. I still get very good gas mileage so it will not effect the operation of the vehicle in any way other than making it quiet.

My older muffler rusted out and I ordered this one wanting OEM noise level. I used rustoleum to paint the muffler before installing to attempt to prevent premature rusting. Installation itself was not horrible if you are handy, but the muffler I received had a rough weld on the inside of the flange and I had to cut and grind the knob off in order for it to even flush up to the pip coming from the engine. Very frustrated that if someone didn’t have the ability to adjust it, they would not be able to install and it was a major inconvenience for me. Sound is perfect for me though.
