what is an optimised bypass valve and idler pulley? and how much is the optimised bypass valve?

also does the Re-Route pipe fit for the US spec MCS? and is it going to kill the exhaust since it is only running one muffler instead of two?

thanks

Hi Mobile,bypass mod is 'a service' rather than an item you can buy mailorder. Please see website for details on theGTT Idler pulley & also the 'almost as important'GTT Tensioner pulley we do. Both extend belt life considerably. No problems with the muffler;whether you have one or two mufflers (stock) all the gas goes through the last muffler as they are in series with each other not parellel.
