First of all; you’ll need to fabricate to make it fit. The o’2 sensors hit the body. Be prepared. Secondly, the way it flows, it gives off bank 1 and bank 2 codes. Thus for the first issue, I added A nut and welded on the o2 treads on the other side. Second, the clamps they give are crap and loosen up just in the test drive. These needed welding too. The driver side clamp also was off, like it created an angle so we had to add shims to even them out so it wouldn’t have an exhaust leak. Lastly; I added O2 fowlers because the ecu kept picking up bank 1 and 2 codes (when originally it only had bank 2). This worked and have heard no other word back from the customer. Not very pleased honestly

This catalytic converter fixed the engine light issue that had been bothering me for weeks. I’m relieved to finally get rid of the error codes. Very satisfied!

Compré la equivocada y el servicio de atención al cliente incluso me preguntó qué pieza necesitaba y rápidamente encontró la correcta, ¡gracias!

Perfect fit, high-quality materials, and the vehicle’s performance has definitely improved. Easy installation and fast shipping!

Doesn't fit up at all and the cats make your expedition sound like a Craftsman lawnmower. Spend the extra money for something better.

Had a small question after installation, they replied within hours. Great support.

Straightforward install with basic tools. Took me about an hour.

Cheaper than dealer, AWD-specific, VIN checked.

Great quality stainless. No leaks.

Ordered at noon, dispatched same day, arrived in 2 days. Tracked all the way. For a small spacer kit, that’s impressive.

Great fit

Perfect fit and easy installation.

Shipping was fast, and the customer service was excellent, promptly addressing all my questions.

good

No more rotten egg smell from the exhaust. These cats burn off the sulfur properly. Cabin air is much fresher now.

Professional and polite communication.

Everything needed was in the box

not bad

The quality is top-notch and feels durable.

Opened it up with zero dents or dings. Top marks for packaging.

Seller uploaded the tracking number immediately after shipment and emailed me when there was a slight carrier delay. Always knew where my package was. A+ communication.

Heavy-duty stainless steel shell with clean, smooth welds. The ceramic substrate looks properly dense and uniform, not like those flimsy thin-wall knockoffs. Feels like quality in hand.
