## Before you buy

- The listing identifies the converter as EPA-compliant and cautions that state rules apply. It says EPA-compliant converters cannot be sold or installed in California and Colorado and may be restricted in some cases in Maine and New York. Confirm the vehicle's emissions certification and local requirements before purchase.
- The listing's fitment is application-specific. Enter the vehicle year, make, model, engine and trim in the fit tool and review any qualifier notes. The 2.445-inch outlet figure alone does not establish compatibility.
- The product information lists material as Metal, while the broader manufacturer description says Walker converters have a stainless-steel body and aluminized pipe and heat shields. The listing does not confirm those construction details for this exact model. The listed 16-ounce weight also appears notably low for a converter, but no corrected figure is supplied.

## In the box

- Catalytic converter (Included)

## A good fit for

- Owners replacing a converter on a vehicle confirmed by the fit tool, who want a direct-fit layout rather than a universal unit.
- Buyers whose vehicle uses EPA or Federal emissions certification and whose local regulations permit this converter.

## Less suited to

- Vehicles requiring a CARB-compliant converter or applications not confirmed by the fit tool.
- Buyers expecting the listing to establish exact stainless-steel or aluminized construction for this model.

## Customer feedback

Aggregate ratings lean positive overall, though a smaller one-star share shows that satisfaction is not uniform. Ratings alone do not identify what buyers liked or disliked, so they cannot establish fit, installation ease or emissions performance for a specific vehicle. For this application-specific part, confirm compatibility and regulations separately.

## Frequently asked questions

### Which Honda Pilot years are listed for this converter?
The compatibility text lists Honda Pilot model years 2009-2015. Confirm the exact year, engine and trim in the vehicle fit tool before ordering.
### Is this converter suitable for every state?
No. The manufacturer says EPA-compliant converters cannot be sold or installed in California and Colorado, and may be restricted in some circumstances in Maine and New York. Check vehicle emissions certification and local rules.
### Does direct-fit mean no welding is needed?
The manufacturer describes a bolt-on design that does not require specialized fabrication or welding. Actual fit still depends on the vehicle application.
### What does the 25K Miles warranty description mean?
The listing provides the warranty description as “25K Miles” but does not detail its terms or conditions. Confirm coverage before purchase.
