i have a 08 chevy cobalt 2.2L 4cyl and was getting code p0420, i bought this converter and it works wonders! no more check engine light and the only brand id ever purchase a converter from.

Great performance mild tone. Nice upgrade.

Easy to install. Perfect fit too

I got the bolt on catalytic converters and performance exhaust for my 2004 Yukon and it went on exactly as it should. The only hard part was taking the old exhaust off. It makes the old yukon sound like a camaro, and it is keeping the engine light off. I am very happy with this product.

Excellent product service and shipping
