Second I have run turn downs on 5 different vehicles and 3 of them were Tahoes. With a good muffler (50 series flow or magnaflow) cab noise is not that bad. I just installed a new cat and a magnaflow single in and dual out with 2 1/4" turndowns and I love the way it sounds but I don't like a loud exhaust. Mine rumbles at an idle and when it is going down the road it is not bad at all but it dumps right before my rear end and the turn downs are 30 degrees. there is my .02

I'm gonna try this!! thanx!!

Scoti is right, at least about my truck. Duals with 2 chamber Flowmasters cut off in front of the axle is just too loud for my taste. I am going to get the tailpipes put back on ASAP!

dumping them is the way to go lol you get to set alarms off its awesome! Dont have to worry about your catbacks being even or falling lol. My trucks running dual flowmaster 40s that dump after the muffler behind the axle. It will rattle a little and the cab will be louder but its a beautiful sound

Just split the exhaust behind my cat converter and added two cherry bombs with no turndowns. Has a nice throaty rumble now. Picked those bombs up at a garage sale for 5 bucks for the pair!!

I have turn downs on mine too. It is a bit loud at idle in stop and go traffic, but once I get up to 20mph or so it is actually pretty quiet. I have a mild big block with full length headers going into 3" X-pipe, then out through Hooker Aerochamber mufflers. The turn downs are angled slightly outward, not pointing straight down.

The humming noise you hear is actually the Holley Blue fuel pump. Now THAT is loud.

I've had trucks that had tailpipes and ones that had dumps, before the axle. I like tailpipes better because I hate the exhaust resonance inside the cab on the freeway. dumps make it louder mainly from the inside of the truck from what I can tell.

I always got one with my 3-spd tranny with the engine about 3000rpm. After a while it'd make me really sleepy.. Maybe that's the grease-monkey's lullaby.
