M3post.com member Shady 1 from Texas. I just had American Racing Long Tube Headers, along with their 3 inch Catless X-pipe installed on my 2008 BMW E92 M3 Supercharged with the VF650 kit. I had the shop Powerhaus-Performance in Cherry Hill, New Jersey custom tune my VF650 Supercharger to the ARH long tube headers with X-pipe connected to my Gintani Race Exhaust mufflers. Roshan is the man, I drove my car all the way from Texas to New Jersey to have my car custom tuned. Well worth the long drive and power. The car put down 523 WHP on their Mustang Dyno. My car pulls like crazy I am very happy with this set up.
