Does anyone know the length of the loudmouth resonator on the "original" loudmouth setup not the new modular system. I think i might change it up with a bullet muffler but im not sure what length to get.

 

Its whatever you want to cut off. I cut roughly about 3 inches from the rear axle. Tossed it all and added a chambered stick right to the Y-Pipe about 28 inches long. Ive never looked back or under the car since. But then again I dont really drive it anyway it just sits there looking nice Ooo the resonator is about 14 inches. Id cut at least 4 inches more off on both sides. This way you can always use stainless bands and put it back when ever you want to.
