The Revos are great looking pipes but stupidly expensive . The DP outlaw system comes with the link pipe . The cats on the roadster are in the silencers , the strange box like contraption that links the stock pipes is exactly that , there is nothing in it except offset pipes and a baffle designed to slow exhaust flow and effectively restrict power ! The outlaws have a 50mm bore size , the only way your gonna soot them up is with a seriously bad tune ! If money was no object , I would have the Revos but pretty pointless fitting performance pipes without the straight through 50mm bore link pipe ! Again , fitting performance pipes is a fruitless exercise unless combined with a free flow induction like Ramair or KnN . No good having the blow if it ain't got the suck . What is it that you are trying to achieve , is it noise , power or both ? If you have deep pockets , change the headers , if you like the balanced look of 2 cans then outlaws won't disappoint , bin the stock induction and get a good tune and you will have a very different beast on your hands ! Hope this helps ?
