Questions

Walker, answered

The questions our support team gets asked most about Walker.

Visit our Help Center
Who makes Walker exhaust products?
Walker is an exhaust and emissions-control brand of Tenneco Inc., operated within its DRiV aftermarket group from Northville, Michigan. The brand goes back to 1888 and pioneered many aftermarket exhaust standards, including the Limited Lifetime Warranty.
What warranty do Walker products carry?
Walker Quiet-Flow SS mufflers and muffler assemblies carry a Limited Lifetime Warranty covering defects and wear-out for as long as the original purchaser owns the vehicle. EPA catalytic converter shells and end-pipes are warranted 5 years/50,000 miles, and premium mufflers include a 90-day Safe & Sound satisfaction guarantee.
Are Walker catalytic converters legal in my state?
Walker makes both CARB-compliant converters for California and CARB-adopting states and Federal/EPA-compliant converters for the rest of the US. Walker is known for industry-leading emissions compliance - just match the converter's certification to your state and vehicle before ordering.
Are Walker mufflers as quiet as OEM?
Yes - Walker Quiet-Flow SS mufflers are engineered for OE-style sound, fit, and performance, with internal designs that mirror original-equipment acoustics. They're the go-to choice for restoring factory-quiet exhaust rather than adding performance sound.
What is the difference between direct-fit and universal Walker converters?
Direct-fit converters bolt into the factory location with no cutting or welding - the fastest install. Universal converters cost less but require pipe cutting and welding to fit. Walker offers both in EPA and CARB versions, so you can choose based on budget and installation method.
