Must be the loudmouth II's, cause even with stock manifolds and cats mine was louder than that with more rumble. Now with longtubes and no cats it is an animal. Mine sounds like this guys^^^, except I dont have that baddass cam idle.

I'm pretty sure its the LM1's. I bought it on ebay from a guy who had it on a trans am. I am running all stock manifolds with cats (we need em in AZ) with stock piping until the pipe then after is a 3 in. elbow to a 4 in. 24 in. long exhaust tip.
this is the lm1 with lt's I had on my old z http://www.youtube.com/watch?v=ZIKd4zsvDWk

I like the sound, it has a nice low tone, but I'm not a fan of the popping, my exhaust does that too Any way to get rid of that popping, or is it a characteristic of the muffler?
