Hi All,
I was looking for some basic mods with best gains, I checked out the RPI and Evosport pulleys for the M5. Anyone see power gains with this mod, and wuold you go RPI or Evosport? I have some basic mods already, taking it slow - currently RPI scoops, Block off plates, BMC filters, RPI cat back exhaust. Next year im going for RPI full system with headers and xpipe.

My Ride: 09 M5 (E60) Interlagos blue, Silverstone interior, with cold weather package. Adaptive Xenon headlamps and adaptive brake lights, hud, comfort access. Comfort seats, basically fully loaded.
go for RPI, i've had it, it did make some diff on the low end torque. Only better thing than evosport is that RPI looks identical to the OEM to keeps you balls safe unless somebody literally takes it off and checks it out. ... GL

RPi Pulley ALL THE WAY! You won't regret it...just ask John@Motorcepts 
As for Agency Power I think their pulley's are made overseas, but not 100% sure. I wouldn't put a cheap pulley on my car and later pay for it if the pulley goes bad. Just my .02

Come on, its a pulley, and its made of of the same materials and the belts used are the same... You can't honestly believe that the price difference is worth it. You just lost a lot of credibility in my book. Agnecy power has been around for years now making quality products. I could see if it was some ebay/noname brand but don't feed us that crap around here...
