These systems provide a noticeable performance gain and were designed using SLP's innovative modular technology. This enables consumers to change the performance and noise-level characteristics by switching from our bullet-style Loud Mouth resonators, to our quieter Loud Mouth II mufflers, in order to suit their individual requirements.
They feature; stainless steel, mandrel-bent 2.5 tubing; polished Loud Mouth resonators and Loud Mouth II mufflers with SLP's logo embossed in the body; integrated PowerFlo-X Crossover Pipe; double-wall polished tips with SLP's logo; easy, bolt-on installation and SLP's lifetime warranty. All hardware and Installation instructions are included.

mid-range tones with moderate resonance

* Volume and sound quality will vary based on engine and exhaust-system specifications. Loudmouth also refers to some systems without any resonators such as the 2010 Camaro Loud Mouth and the 2005 Mustang Loud Mouth Axle backs where the mufflers are removed altogether.

Ownership: 1 month - 1 year
This exhaust added a lot more horsepwer and sound mean amd loud!!!!!
Jba headers k n intake loudmouth exhaust and diablo superchip
Personally the install was easy, directions were simple. Fit and finish is good. I love the sound that it delivers, not so much for the wife. I warned her for over 2yrs this was going to happen. Now, she isn't so pleased. I even got a guy with a Viper RT/10 to snap his head and give the thumbs up! Noticed a gas mileage increase already, as long as you keep your foot out of the pedal! With the 4 cyl shut down, you can really hear the note change at cruising speeds, and I think it makes it easier to stay in that fuel saver mode. Thanks for the product, really enjoy it.
