I have a 2005 F7 SP DD and am geting the Bmp stealth pipe and was wondering if any one out there is runing there can with it or just the can? Many cans are Dnyo proven to lose hp, and have poor back pressure. Is this can much like the rest, from what I have read it dose not improve any but you don't lose. Any opions or info would be very helpful. I was also intersed in the BMP clutch kit or ODS dans any thoughts on witch to go with? Oh and how dose the can sound?
