Flowmaster Direct-fit Catalytic Converters - 49-State Legal Reviews


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

Reviewed By Shannon W (PLAIN CITY, OH) Reviewed for a 2003 Chevy Avalanche —7/18/2015 4:47 AM

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.

I absolutely loved the sound every time I start up the engine. Took a while to install since I didn't put it on the lift. But it is definitely worth it! Got it when it was on sale and 75 dollars rebate... 5 stars!

I love the new Flowmaster super 44 muffler, it sounds just the way I wanted it too. The aggressive sound it puts out brings the 5.3 Avalanche alive.
