Long Tubes, ORY and GMMG??

I'm installing long tubes with ORY, but was wondering if the GMMG would be too loud? I don't want to get pissed off when I go on a road trip from the exhaust droning. If you could attach some sound clips, and let me know your opinions it would be greatly appreciated.
Thanks

I have GMMG with cats and it sounds great. LS1s with the ory and GMMG sound raspy.

hope that helps :o
the avi's were with a different camera that was starting to crap out on me, also worse sound quality I guess, all driving videos were windows down and I don't think I hit very high in the rpm range... I should probably do that at some point.

i should still probably buy a set of the oval tips, just haven't wanted to shell out the cash for them after over a year... they do have a different effect on the exhaust note cats or no cats... i kind of regret not getting them so far, but I was going to get other tips at some point

I tried it but couldn't take it. Way too loud and extremely raspy. Had to go to cats and a powerpack in the I-pipe to balance the sound.

when that exhaust was built it was made to run with cats.. Without them its going to sound like a LM exhaust very raspy . My advice is if you dont want to bother people go with a Y with cats. So you can get the gmmg sound ;-)
