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!

Gibson Exhaust Performance Headers Reviews


A must buy for any vehicle!

Reviewed By Robert M (MEMPHIS, TN) Reviewed for a 2012 Chevy Avalanche —6/4/2014 9:07 PM

These headers instantly provided more HP and gas mileage. If you are on the fence about purchasing headers, you shouldn't be, these headers are exactly what I was hoping for. I've purchased a cold air intake, gibson dual exhaust and superchips power programmer over the past years. The headers provided the most noticeable HP and MPG gains. Only issue was the lack of detailed instructions when removing exhaust manifolds. Additional tools required, O2 sensor removal required and not mentioned.
