Blocko Posted June 5, 2017 Share Posted June 5, 2017 I know the japspeed systems are fairly frowned upon but I've spent a lot of time on youtube looking at different systems and the K1 sounds and looks good. Thinking if I get a used one the fitment issues will hopefully already be tweaked and it should be nicely priced ðŸ‘🻠One question though Japspeed only list it for the older models. I have a rev up. Yet the cobra system is listed all the way to 06. Do the rev ups have a different set up? Thanks Quote Link to comment Share on other sites More sharing options...
Jay84 Posted June 5, 2017 Share Posted June 5, 2017 Pretty sure its only the HR's that is slightly different, the revup and non revup are the same. Quote Link to comment Share on other sites More sharing options...
