Flowmaster Super 44 Series Mufflers Reviews

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.

2007 chevy avalanche 3 INCHES IN AND DUAL 2.5 INCHES OUT.

Reviewed By christopher p (Spring Hill, FL) Reviewed for a 2007 Chevy Avalanche —2/7/2009 4:23 PM

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.
