i have a 01 blazer xtreme and i'm curious if i should get 'single in single ou't or 'single in dual out'...its a 4.3 and i'm going to dump it instead of run through the tailpipe. its gonna be slammed on 22's shortly so by all means its not a 4 wheel drive vehicle so i don't want it to sound like one, i just want some type of rumble...any input

 

Flowmaster 40 series are ok for our 4.3's IMO. I have been telling alot of people to check out youtube or streetfire.net and listen to sound clips.

The worst I heard on a truck was a glasspack and some chrome muffler with a 4" tip. It was a V6 butand notChevy.

 

yip, the 40 series sounds pretty good.......alot of people also like the dynomax........
