i recently put on a new dr.d slip on onto my 01 rappy. all i can say is wow. this thing amased me at the amount of bottom end and mid range it added. my clutch was slipping until i installed my new ebc today. now i can realy feel how hard it pulls. i also put in a dyno jet kit. 148/150 on the mains. i would recomend this pipe to anyone who, like me rides mostly open trails and some sand.

 

Cool!............Glad it runs good for ya. Was it a big difference over stock? My HMF full system is on its way and I'm also going with a Dynojet kit and removing the lid. When I called DJ to order a #155, they told me that a 170/175 would run best for my set up.........[img]i/expressions/face-icon-small-confused.gif[/img]
Maybe they were just trying to sell me more jets...........[img]i/expressions/face-icon-small-happy.gif[/img]
