When I purchased my Camaro, it had the stock manifolds, cats, and a LM1 catback. Honestly, it wasn't too harsh for daily driving at all. Even the girlfriend didn't mind it and it wasn't difficult at all to have a conversation in the car or listen to the radio at a moderate level. However, like SSmoken said... once you go Longtubes (at least with an off road y), it's insanely loud. Rasp like you wouldn't believe too. After a few trips of mind numbing noise, I finally switched to a Magnaflow, and couldn't be happier. Fitment was kick ***, and the look of the quad tips made my SLP look like ****. From this example, I honestly believe the Loudmouth is going to be louder for you in all aspects... driving around, wide open throttle, but still tolerable. I wish you could find a LM2 sound clip... does your Blackberry do YouTube? I typed in a search with "LS1 Loudmouth 2" and got a few links to come up. If it works, give it a shot. From what I've read, the LM2 is quiter than the LM1 with little to no difference in power loss. Good luck man. Sorry for the long post.

Decisions, decisions. If I knew the magnaflow with the 4x4 tips would look okay I'd just get it with a lid kit...if its worth it. I may just get a K&N filter and lid. Anyone got a picture of the 3.5 tips on a trans am? I'm going to try a search real quick...

When I bought my exhaust I bought the LM2. Fits great easy as hell to do. The resonators are easy and pretty cheap so I thought I would try the LM1. It sounded good, but the LM2 has a deeper more throaty sound to it. Now with my shortys and my ORY it sounds awesome. Never to loud, but never to quiet. Do yourself a favor and listen to Detoxx's videos. The powerflow sounds amazing.

I vote lm1... I think it sound good! I had a SS with full slp system on it from longtubes all the way out the back with LM1 and I like it... But yah it was DEF loud... I think the magnaflow is a little to mellow for me! For kind of what your describing i'd go LM2 though....

here is an all stock ls1 with slp loudmouth catback. Not sure which version, but its the one with the small bullet style muffler.
