You don't know what loud is yet. 
Like or dislike
NOOOO.Too loud and RASPY IMO. Sound GREAT stock though. And if you ever add a cam you will really hate IMO...
LM2 sounds a little better and a lot guys run a borla or other bullet in the I pipe to tone it down with either the 1 or 2 or more commonly just replace the resonator with the bullet. Still loud as f@ck but not as raspy....

A little too loud for my taste. They are alright with a catted setup but still have some rasp in them. I would try and get some kind of bullet muffler in place of the resonator. Will clean it up a lot.

yeah i've had slp exhaust on my car now for 4 yrs now with about 10k miles on the system... Then I have headers installed and I had no Idea it would be that LOUD... Time to put on flowmasters on their now haha... Thanks guys for the comments...
I'm a bit biased (take look at my signature), but...
...with a Catted Y, I like it.
Its loud and unrefined, but sounds good to me.
When I eventually do an aftermarket H/C swap, my opinion may change.
I haven't ever heard LM1 with LTs and an ORY in person, so I can't say whether I like it or not.
All the videos I've seen with this setup seem like it'd be pretty obnoxious. But I could be wrong.

i honestly like the LM1..it is very loud.. may not be clean sounding but its got its own sound and tone. to me it seems like most of the catbacks all sound the same on a fbody.. just my opinion though.
I thought the LM1 sounded great with factory manifolds and Y...as soon as I put on LT's and ORY =
Sounds great again now that I welded in a Borla XR1 where the resonator was.
I have heard 2 different cars with LMs in person. One was a bolt ons only, the other a head/cam built car. Both sounded absolutely terrible. One guy added a borla xr-1 bullet muffler, the other ditched the loudmouth all together for a different cat-back.
