Warranty

Limited Lifetime Warranty

Walker warrants qualifying exhaust products against defects and wear out when used on private passenger cars and light trucks under normal operating conditions for as long as such original purchaser owns the vehicle on which they were originally installed. Rust/corrosion damage is not covered by this warranty.

Walker’s obligation under this warranty is limited to replacement of the worn out or defective product with the same product in accordance with this warranty. Any incidental and consequential damages are excluded under this warranty, regardless of when the failure occurs. This warranty does not apply to products which have been modified, improperly applied or installed on vehicles used for commercial or racing purposes.

This warranty gives you specific legal rights, and you may also have other rights, which vary from state to state. Any implied warranties you may have under state law are limited to the same duration as this warranty. Some states do not allow limitations on how long an implied warranty lasts or do not allow the exclusion or limitation of incidental or consequential damages, so the above limitations and exclusion may not apply to you.

No Box?

Part is fine but not sure if it was dented when shipped or got dented on the way to us. But it wasn't in a box so it was dented. Got 2 parts both not in box and both dented.

Exact Fit, Runs Great!

Tried another brand and it was very poorly made and would not fit. Ordered this unit and it bolted right up and fit perfectly.

Great Replacement

I replaced the OEM header/cat about three months ago. It resolved the 'check engine' light I had. More importantly, I haven't seen a decrease in power or fuel efficiency at all. This was a concern initially because the design of the Walker header doesn't appear to allow exhaust gases to move as smoothly. Great product overall.

The part is used, not new. The price is too much for used part.
