LM2 is obnoxious and LM1 is even more obnoxious

LM2 is a little more mellow then the LM1.

The loudmouth 1 is less restrictive, therefore it is louder and supposed to make more power. I have a LM 1 and it sounds sick, just dont add headers or highflow cats to it, or it will sound like ***. http://www.slponline.com/modular_exhaust.asp

Go to that, on the bottom there is 3 pictures of SLP three mufflers, just put the the arrow of your mouse over them, and it shows what the mufflers look like on the inside, that should give you an idea

The muffler is different. But all LM's are now modular which means you can swap the muffler. There are actually 3 different mufflers available from SLP.

Personally I'd go for the LM1, it's Louder and IMO nicer. If you don't then like it you can swap the muffler out. Although it'd be cheaper to replace it with a muffler from Magnalfow or Borla and arguably better sounding than the LM2 muffler.

Lt headers are fine, but IMO I would advise running CATS with the LM as it will improve the sound quality. High flow cats won't cost you any HP either.

lm2 is quiter then lm1 i have lm2 and love it, its not to loud at idle (nice rumble), and at wot opens right up and sounds awesome..... i dont think there is much of a restriction diff. between the 2.

The LM1 uses a resonator instead of a muffler..........very loud. The LM2 uses a bullet muffler........It's loud, but not a obnoxious as the LM1. I bought a LM1 and didn't like it. It depends on your personal preference.

it says its a muffler for the loudmouth 2 but it has no baffles inside as a muffler would, there is no restriction threw the "muffler" and should be considered a resignator in my mind

The resonator on the LM1 is actually a muffler also, its a form of deflection chambered muffler not that disimilar in function to the mufflers used on the GMMG exhaust.

i agree, but neither of them are convention type mufflers and restricion is prolly identical between the 2

so the loudmouth one is louder but getting lt headers and a ory wouldnt be a good idea with that exhaust, right now i have the flowmaster catback on my car and want something that flows a lil better and sounds louder

almost anything would flow better then chokemaster, if you get loundmouth1(the louder of the 2) or loudmouth2 you should be very happy, both flow and sound way better then flowmaster

LM1 is the same as a Dynomax Bullet.....LM2 will slightly muffler the car...but still loud If your goin to buy LM1, go buy a Bullet and save a couple bucks...

Camaro94SS

Well....im goin to have LT with ORY and cutout always open...my buddy has a T/A and thats what he has...ist ridiculously loud at hard acceleration,but if he drives slow,theres not enough pressure to push the exhaust out the cutout and it just flows throughout the exhaust....IMO it wouldnt be too loud...but thats jsut me lol
