Exhaust Tips for cutting down DB level
I did a search on this forum and cant seem to find a thread for exhaust tips that curve downward to cut down DB.
Where can I find these since I hear they can cut down DB levels by up to 4 DB ? The reason I ask is I am close to being over the max DB level for a local track that I have signed up for and 4 DB would assure Im fine.

Contact CYBA on the forums. He had muffled tips for sale. Not sure if he has any ready for the M3, but worth asking. They were nice and double walled.
