Flowmaster American Thunder Series...

[chevy4x4trucks]

Just got the new exhaust installed after a long backorder delay.  I took it to Midas and they did it for 50 bucks.  Not a bad deal.  But, I've got to say, flowmaster lives up to their reputation.  The truck sounds great now.  You can actually hear it start up.  And when you rev it people will know.  So far it's the best thing that I've done to the truck.  The only thing I want to change on it is re route it so it comes out on the sides of the trailer hitch.  I apparently go the one that angles out both sides behind the tires (not what was in the picture when I ordered it)  I'd send it back to get the correct one but I don't want to wait another month.  But if you want the best sound possible go with a flowmaster.

I agree. I've had mine for over a year now.  I can't imagine how I got along without it.
