For Sale: Radenergie E60 M5 Exhaust. Originally paid $3700 and was only used for one month. the selling price was $2000 plus shipping and paypal but is now lowered to
$1700.00 shipped. I was able to find a few clips and dynos of someone else's radenergie e60 m5 exhaust.
The dyno states a stock M5 is 385 to the wheels, the exhaust gained 22.4 hp to the wheels: 407.4 WHP

"Here are some videos and the dyno sheet. The dyno is based on rpi ram air, and radenergie exhaust (sections 1, 2 and 3). Note, a stock e60 m5 dyno's around 385 to the wheels on the dyno dynamics machine. The dyno sheet below, shows 407 to the wheels."
