I am running a EruoRace header, and the "Turbo" muffler is LOUD. Ear plugs needed on the freeway loud. yes, it sounds mean, but it makes the car rather uncomfortable to drive for longer rides.
I would like to cut it off, and replace it with something a bit more quiet, but that will still work in the spot and allow me to use the stock exhaust exit in the rear valiance. Any ideas? Zach |

Its an aftermarket unit that replaces the cat/crossover pipe/muffler. Mine were just about rusted to nothing, and since I don't need to get smogged in this fine state, I ditched it. Unfortunately the muffler is small and probably has little in the way of baffling. Even just a perforated metal cage with an air buffer between it and the muffler wall I think will help deaden the sound. I am tempted to cut open the stock muffler I have to see what VW did in terms of baffling/sound deadening and try to replicate it in this aftermarket unit. The stock one was nice.
Chris, what, in terms of baffling/sound deadening, is inside that killer muffler you have pictured? Or is it just an expansion chamber? Or are the guts top secret? -Chris |

It's essentially two EVO II Silencers back-to-back; only a semi-secret. (IMG:style_emoticons/default/biggrin.gif) There is an "expansion" chamber, two types of sound absorbing media, and multiple sound reflective surfaces that don't interfere with the exhaust flow. |
