Might have to put the LT's on and see, I noticed very little difference going from Gibson shorties to StainlessWorks LT's and catted y-pipe. Once I gutted the cats it got hella loud though.

 

Well here is the current set up.

Sound decent to me. I'm more then happy with it. There is only a HINT of resonation at APPROX 1300RPM but you REALLY REALLY REAAAAAALY have to listen to it.

Idle is about as quiet as stock, maybe a tad louder. Cruising/accelerating slowly sounds smooth and you can hear the rythem of the v8, and its very quiet. When I stomp on it, it gets loud, not as loud as it was with the magnaflow but its there.

 

give it time it will change sound, thats a glasspack muffler/resonator, cheapest muffler around, the glass inside will come out
i have a 12" with 3" pipe from the flange, and it makes a 90*turn and shoots out the side infront of the tire
mine resonates like crazy, did it with the 5.3 and its worse with the 6.0
i will be getting a dynomax VT, jegs has them for 75
anyone seen this
