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.

Best Bang for Buck

Reviewed By Matthew T. I (Williamstown, NJ) Reviewed for a 2003 Chevy Avalanche —5/15/2014 8:09 PM

A very nice exhaust system, well priced as well. Going from no muffler and no pipes to this system, it was so quiet I didn't even think my truck was on! Very quiet, but for the Avalanche I like it bc my truck already has good sound-proofing. Installation was easy I did it myself in a 1/2 hour. Looks like it will last a long time I hope so. If you're looking for a well-pronounced "throaty" sound, this isn't a system for you. The price & quality is what makes this system stand out. 4 of 5 stars.

JBA Performance Exhaust Reviews

great price, great sound

Reviewed By Mark S (Farmington, NY) Reviewed for a 2003 Chevy Avalanche —6/14/2012 6:04 AM

I was very pleased with the sound of this exhaust. It is hard to figure out what something will sound like until you install it. It is not overbearing, but you definitely can hear it inside and out. At cruising speeds you barely hear it at all. For the price considering this is stainless it is a great exhaust. Very happy so far.
