SLP’s Loud Mouth lineup of exhaust components is very popular in the after market realm, it’s actually one of the most popular systems for the fourth-generation Camaro and Firebird. What’s interesting about this is that the Loud Mouth system was initially designed for a different breed of American muscle, the Ford Mustang.
Here’s what had to say about the Loud Mouth resonators to the dudes over at LSXTV.
“We’ve sold literally thousands of systems for fourth-generation F-bodies alone. I couldn’t even guess right now how many we sold overall, because enthusiasts adapt the resonators to vehicles we don’t even offer kits for,” said SLP’s Kevin Woodruff.
It’s true, we’ve even seen SLP Loud Mouth systems used by Cobalt SS owners to give their four-bangers some “authority.” But not GM Authority.
Not all Loud Mouth resonators are ear-piercingly loud, so don’t worry if you’re not into that sort of thing. SLP offers two types of resonators to fit your demands. There’s the original straight-through design, this one is for those who want to hear it all. For those wanting to tame it down a bit, there is the Loud Mouth II resonator that features a wrap around the perforate pass-through pipe. SLP was smart and revised their welded design to use leak-preventing torque clamps that would allow owners to easily change their Loud Mouth resonator.
If both the Loud Mouth and Loud Mouth II are too loud for your taste, SLP has come up with the PowerFlo conversion, which essentially attaches two SLP mufflers to the exhaust system, quieting it by about 6dB at idle. Not a huge difference, but it’s still noticeable.
