There are various units from many manufacturers on the market. Only a few have any proven worth and performance inprovements. Note that many are built using steel and will rust. The OEM BMW unit is very efficient to begin with. If you want a little more tone, w/o a drone at any speed, and documented improved flow for street or track use consider the RAVEN. This unit is handbuilt, all SS construction and has authentic mitred DTM tips each 3" in diameter! Contact me at the url below for pricing info.
Scorpion, Borla, etc
