I think Catted sounds pretty good.

 

with my setup the lm1 is crazy!!! if you are going to go with lt's, a cam, and other mods like that, go with another setup.

 

i had the lm II and i loved it and got alot of sounds good from people. i added the edelbrock long tubes and ory and i still love it, i have some vids too.

 

I had the loudmouth 1 on my 94 B4C, and I liked it a lot...My friend could hear me from his work when I was a few blocks away...I loved the overall tone, but the drone at low RPMs got annoying after a while, especially if I had a headache or was sick...It made me not want to drive it on those days...

 

I have the full SLP exhaust setup and I love it!

 

I've got the LM1 on a 98 Z with SLP's lid, stock Y and headers. The quality is definitely there, and the sound and look are great as well. WOT=heaven, "drone" on the highway=heaven. If I wanted a car I couldn't hear, I'd buy a Lexus. Love that V-8 growl...

 

Havent heard one person say they dont like the way the LM1 sounds on my car. Eventually I am going with LT's and cam and am still on the fence about catted or OR y-pipe. Great quality and easy install unless u have no sawzall like me and had to hold the blade of a hack saw in ur hand and cut the **** outta the old exhaust to get it off due to not having a lift (although that was a problem with stock not SLP hehe)

I have the lm2 and it sounds great on stock manifolds. I will add headers and a cam tomorrow and looking forward to it. Everyone will bash the Loudmouths but they sound mean as hell. The lm2 is a lot quieter than the lm1. And like someone else said every catback will have rasp. I would reccomend it to anyone.

 

hey jacob, when i bought my car it had the LM1, i hated it, too much drone and resonance inside the car, had to talk louder and play the stereo louder all the time, so..........i said screw it and yanked it off

 

i had LM1 for a year and loved it. now that i went to headers and ORY i hate it. lucky i live in the middle of no were

 

I finally added headers and a cam and it sounds mean as hell. Definitely louder than stock but not crazy loud until wot. Excellent sound and quality!

 

04 GTO here with LM1. Sound is great, especially with it being a true dual catback with x pipe. The fitment is crap though. It bangs against my drive shaft despite the several tweeks i have given it. My Kooks Lt's are on order, so im waiting for all hell on earth to be released once installed. My neighbors are going to love me.

 

I love my SLP Loudmouth.
I might switch to a Borlamouth when I get my new Jet Hot LT's, we'll have to see how it sounds.
The 3" Stainless Steel is nice too.

 

I installed my LMI last week. I don't mind the drone in the city, On the highway i can here it, i suppose on long drives it may get to you, but i like a loud car. The system was a little trickey to get adjusted on my SS. It just clears the rear support arm and seems to vibrate on it at times.

 

If you guys think replacing the LM resonator with a borla or magnaflow bullet muffler sounds good then look up the chambered mufflers.

 

since I installed my headers and cam I have gotten only 2 people say its loud. One guys has a v6 mustang and the other is my 77 year old uncle but other than that nothign but compliments.

 

Detoxx, is your Y-pipe catted and do u have any sound clips?

i'll never forget the smile on my face when I started my car with the LM1 for the first time.Couldn't have been more satisfied.Hell I didnt listen to the radio for a week or two haha

My y-pipe was custom made w/o cats. I working on getting some videos up and a scan of my dyno graph
