loud mouth I or II 
loud mouth I or II
The loudmouth is VERY loud. I loved it when I had in on my SS with FLP LT's and ORY. Granted with my FLP's I could throw the cats in, but it was still louder than all of my friends cars with similar mods. Some people try to trash the loudmouth, but IMHO it is one of the meanest, most vicious sounding exhausts that you can put on your LS1/LT1 car and with LT's it's better. It sounds way better with a catted Y though. The only bad thing is that every time you get on it, everyone in a 2-3 mile radius will hear you=cop magnet. It does have some drone, but I shifted around the ugly spots. I went with the borla on my Hawk and I love because of the look, sound and adjustability. Not to highjack the thread.....the loudmouth sounds great, is light weight, stainless steel, and won't kill your pocket. The I've heard both the LM1 and 2 in person. They both sound good, but make no mistake, the LM1 will blow any cars with equal mods out of the parking lot at a cruise in. The LM2 has a slightly more refined sound and only slightly less loud. The LM1 highlights a raw, unrefined LS1....both the good and the bad....but way more good to me. Good luck with your selection.

I love my LM1. Absolutely awesome sound at idle and at WOT. However, I'm running open headers right now and don't really feel like putting it back on 
IMO, you really can't go wrong with either.

If you don't like the tips you can always slap some new ones on there too. 
I have the LM2 with XS Stainless LT's and a Texas-Speed catted-Y, here is a video clip.
