I dont get it. My old setup was factory manifolds, cats, all the way back to right behind the cab with a dynomax ultraflo X. it was fairly loud. So i got set of longtubes, threw them on had a muffler shop reuse my cats and muffler. looks like they used smaller pipe than the factory dual setup. looked like from the factory it was 2 3" pipes going all the way to muffler the new setup is smaller with some reused pipe.muffler is like 6 inches further back also. it is DEFINITELY alot quiter and lost alot of its tone.could the smaller pipe attached to the larger pieces attached to the cats have done this? I really dont get it. long tubes=quieter? im about to order the off road y pipe and turn this true dual setup into a a single 3" setup with a borla xr-1

The exhaust I had on mine was factory manifold and y-pipe with a flowmaster cat-back that dualed out the back.
I took that off and put LT's ORY Resonator and Borla Xr-1 running 3" all the way and its about as loud as the other setup. Resonator didn't seem to help a whole lot so I may take it off to see.

The smaller pipe might have been the Difference in yours. But it's hard to say for sure.

Lt's mellowed out my sound in cab for sure. I think it has to do with less restriction in my exhaust, better flow.

Sounds like a great setup. I think the samller pipes made it quite.
