We've been ordering from Accurate OEM for over a year and haven't had a single comeback. The quality is indistinguishable from new OEM and the price is about half. It's become our go-to for catalytic converters!
I was skeptical about remanufactured converters at first, but Accurate OEM changed my mind fast. Bolted right on, passed emissions first try, customer was happy. Their team made it easy to order the exact right part. Saved me hundreds!
