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 |

My experience with mufflers in general, especially low restriction mufflers:
Bigger = Quieter If you could fit (tow?? (IMG:style_emoticons/default/biggrin.gif) ) a trailer size empty BOX on the back, with just an inlet and outlet matching the size of your exhaust, I'd bet it would be whisper quiet! But we're all limited on space. So it comes down to either OEM (pick a high output engine from and OEM manufacturer to choose that muffler from), or the biggest high flow aftermarket muffler that'll fit. The 'trapp might be a good idea, basically adding a 2nd muffler, and you could "quiet" it further adding more restriction with fewer plates. Might do some funkiness to the carb jetting though????

This is probably the biggest muffler that will fit well under a 914. It is also about the quietest available, except for (possibly) the OEM units. It is without a doubt the most free flowing, since it doesn't add any length to the primaries and has nearly zero internal restriction. Oh, yeah - it is quite likely the most expensive muffler available for the 4 cyl. HEs too.
