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.

I HAD MY 40 SERIES WELD ON AT A LOCAL MECHANICS SHOP, BUT INSTALATION WAS STRAIGHT FOWARD. I LIKE THE SOUND, BUT I THOUGHT IT WOULD BE LOUDER THAN IT WAS. NEXT FLOWMASTER WILL HAVE TO BE A RACE 40 SERIES. I DIDNT NOTICE ANY PERFORMANCE DIFFERENCE EITHER, DONT KNOW IF I WAS SUPPOSE TO THOUGH. OVER ALL WORTH THE 80 BUCKS I SPENT.

Mitsubishi wanted $1700 to fix my catalytic converter. YEA RIGHT. I bought this flowmaster cat and had my muffler guy weld it on for $25. All together I spent $135 and it passed emissions inspection with flying colors! Thanks Autoanything!
