I have filmed a Porsche Manthey 997 GT2 M600, tuned by Manthey Motors. Although it looks like stock from the outside (expect the bigger exhaust pipes), the engine is heavily tuned. This M600 is based on a stock GT2 (530HP), and now it's tuned up to 600HP.Follow me:1st Channel: http://www.YouTube.com/GUMBAL2nd Channel: http://www.YouTube.com/GUMBALTV3rd Channel: http://www.YouTube.com/CarChannelClassicFACEBOOK: http://www.fb.com/GUMBALTVINSTAGRAM: http://www.instagram.com/GUMBALTVTWITTER: http://Twitter.com/GUMBALTVhttp://www.gumbal.tvThanks you for watching my videos.
