i have the rumbler and couldnt be happier. the difference is that the loudmouth is stainless and the rumbler is coated. the loudmouth uses a resonator and the rumbler uses a dynomax bullet. the hp gains should be the about the same for both. and the only place i know of that sells the rumbler is texas-speed.com

I had the rumbler back when I had no mods on my car. I liked how it sounded with stock manifolds and cats plus it was super cheap. only problem I had was driving it in Chicago winters rusted it through in 2 years right where it clamps to the Y pipe. Since you live down south though that should not be a problem for you. LM will be louder LMII will probably be about the same as the Rumbler and as was stated the LM series exhaust is all Stainless.

Rumbler is pretty much a non stainless dyno-mouth. There really isn't much of a hp gain from any catback, it's mostly just sound. I have a LM1 and I love it. I'm on stock manifolds and cats for now, after that I will most likely go to TD's

The Rumbler is better compared to a Loudmouth 2 IMO. As noted, the difference is the Loudmouth 2 is stainless steel, plus it comes with your choice of tips, slash cut or dual/dual style. The Loudmouth 2 is a better deal IMO since it'll last forever where the Rumbler will rust up and doesn't come with tips. By the time you buy tips, for less than $100 more, you could have a whole stainless steel system. IMO, the SLP catback is the better value when you take into account longevity.
