my buddy just had his put on his 5.0.. it has mac shorties and off road h pipe.. its loud at idle and as loud if not louder than straight pipes because well, it is straight pipes.. its way to loud all around.. but thats the lm1... and by the way, on an ls1 with cats and stock manifolds the loudmouth doesnt rasp much and sounds good.. its when you loose the cats that it starts getting really rediculous

I had a 95 lt1 with mac mids, off road y and the loudmouth 1, it was cool for 2 days. It got old real quick and its hard to have a conversation while driving anywhere on the express way or just idling at a stop light. I would steer away from it.
Um I believe Stanger is asking about the Loudmouth II system so yeah all the posts so far are well...... 
Sorry Stanger I have no personal experience with that particular system just thought I'd try and get this back on track

A LMII is alot quieter than the LM1 for one reason only.
A Loudmouth is basically 3" Straight pipes, and you WILL notice a power difference. What defines the sound is the Resonator, or Muffler. It looks like a big can, or glasspack if you will.
The LM1 has absolutely no packing, its just straight through, hence why they call it a Loudmouth. The LMII has packing in it to quiet it down some, and it works quite well.
Its very simple to change the "muffler". Dynomax, Borla and other companies make resonaters you could replace the SLP can with to change the tone some.
With the LM1, there is virtually no backpressure. Its a great exhaust and about as loud as your going to get for a stock car. With headers, I recommend a highflow cat, or leaving youre present one alone. Punching it out will cause a gas like smell, and you'll only gain about 5hp, all this and besides the fact, it's going to be very raspy.
I love loud exhausts, thats why I chose the LM1.

Just get the Rumbler CB instead. Pretty much the same thing, except instead of an SLP bullet you get a Dynomax bullet, and it's aluminized instead of stainless. If the stainless is really worth it to you then cool, otherwise get pretty much the same sound with the Rumbler, and spend that extra cash on something else, like getting someone to weld it all up for you and a tank or 2 of gas and an 18 pack

I don't think the LMII is loud at all. The LMI doesn't even do it for me. I would drive around open headers all day if it didn't make me such a target. 
I love loud cars. My friend has LMII on his stock T/A and it sounded very tame, but had something to say when he got on it. It is very passive aggressive if you will.

If you have a formula or t/a, smoked tips ftw. They look great. Do add a bit to the cost though.

I posted a link for the TSP Rumbler in your other thread.... lol
Personally I like the LM. I think its a love hate exhuast. But if you like LOUD in your face quite evident I'm driving a V8 type of sound then it's hard to beat. I think running it with cats is better than not. But I really don't know whta this rasp is people speak of?
The LM 2 is quieter than the LM, but I've heard mixed views about it. Some claim the LM2 drones more, but I hinestly don't know. The LM's are modular, so if you buy one you can buy the muffler for the other and swap between.
Personally I'd go for the LM1, if you found it too loud then simply swap the muffler out. Although I'd probably go for a Borla or Maganflow bullet muffler over the LM2.
