Flowmaster Direct-Fit Catalytic Converters (Federal EPA-Compliant)

relatively easy to install, good quality, 1/2 the cost of OEM.

The internal monolith in one of my factory cats broke loose on my 2003 Avalanche which is a common problem in GM trucks of that age. It was rattling around and caused a catalyst efficiency check engine code. GM Dealer wanted $1500 to source and install their $800 part. The chat window opened and a parts specialist confirmed fit for my application and even knocked a little more off the price. They beat Jegs, Summit, Rock Auto pricing substantially.

The only problem was that there is a part that you need to save from the old pipe (where flange hooks to the exhaust manifold, there's a little part that fits inside the exhaust manifold and inside the flange from the cat), if you don't save it you will leak exhaust and it'll sound loud. I'm very pleased with the product, they look nice, perform well, and install pretty easily. View more reviews...

Check Engine Light On! What Do Those Codes Mean?

It was a chilly night in Montana, but crystal clear. I was standing next to my Honda, taking in the majesty of the great arc of the Milky Way. Using a cool app on my phone, I tracked the International Space Station and saw it fly above my head at 17,000 miles per hour. It’s […] The post Check Engine Light On!
