the most quite porsche exhaust for a cup car and original porsche motorsport quality is the one from carrera cup UK. It is as quite as a street car below 98 db.it use the extra mufler of teh stock gt3 on both sides and some otehr parts. it cost no power or not noticable

For us with the 09 cup we blew 99 and 100 db at laguna on a nice day with no cloud cover.

Surfbum, Can you post some pictures of what your shop did with your exhaust?
I can build whatever to make it pass I just don't want to buy the wrong 300-400 dollar a piece mufflers from burns and find out they are not quiet enough or overkill.

I have been considering the mufflers from Spintech because they are used on actual race cars and have been accepted and/or required by the sanctioning bodies to meet certain dB limits.

Any one use them?
