According to Harley the bike does not need an EFI remap for the slip-on exhaust alone. I found the Sporti to run well but it sounded a little lean. I added the TVR system and the bike ran well. When you add higher flow intake the stock system does need to be remapped. The TVR covered for this fine but it did not get some of the improvements like higher rev limit. I did have the Harley-Davidson Screamin&#39; Eagle EFI upgrade done along with the plug wires. The Sporti runs awesome with these updates, great throttle response and power. <br /><br />Needless to say, the 2008 Sportster is fuel injected, no carbs. I would think the slip-ons and a higher flow intake on a bike with carbs would require re-jetting. <br /><br />Good luck and have fun!Davidhttp://www.blogger.com/profile/09750556202046170511noreply@blogger.comtag:blogger.com,1999:blog-6468701377763418670.post-21557494721713775102010-06-14T14:06:51.142-07:002010-06-14T14:06:51.142-07:00pipes look and sound great. good question about the remap- I have heard both yes and no with slip-ons but no idea with these ones...<br />b<br />www.americancustom.comAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6468701377763418670.post-73995819436088230152010-06-10T12:50:44.833-07:002010-06-10T12:50:44.833-07:00Did you need to do anything to your carb to match your pipes or was it just plug the pipes and go? <br /><br />I&#39;ve got an &#39;05 XL1200C and I might consider pipes once I&#39;m done w/backrest, Mustang seat and windscreen.<br /><br />Thanks!Chgowizhttp://www.blogger.com/profile/02052820400496340137noreply@blogger.comtag:blogger.com,1999:blog-6468701377763418670.post-50916394373184272022009-06-14T19:57:28.000-07:002009-06-14T19:57:28.000-07:00Sounds pretty cool. I have been dying to get my 06 883R sound louder, not too loud. This probably the best solution. Gotta check how much this is gonna cost.<br /><br />ThxAnonymousnoreply@blogger.com
