First time to forum. I have a 2002 avalanche 2500 with the 8.1 liter and 4.10 gears, 6 inch RCD lift, 35 inch tires, AEM Brute force air intake, Gibson single exhaust. I live at 6500 feet. My question is this, which magnaflow muffler is the best for sound and performance? I am not happy with how quiet the gibson is. I don't want excessive resonation or droan. Any suggestions would be helpful. Thanks

 

I can't say about magnaflow, if you do a search on the main page you will find several threads about this subject though. There are some real nice setups here. I have a similar setup (getting rid of gibson) and I am going with FLO-PRO #2504. It is getting intalled today and I willlet you know how it sounds tomorrow.

 

Corsa! Corsa! Corsa! It's the shizznit.

 

SPINTECH, SPINTECH, SPINTECH sounds like no other

 

Corsa gets another vote here.
I would check out the new Cherry bombs. www.cherrybomb.com
They actually sound really good. There are actual claims of HP/TQ increases.
Seems like a nice product to try.
You'll sure be different than everyone else too.
