With just changing the exhaust, the motor is not sucking in any more air but there will be less restriction on the exhaust being pumped out which means there will be an imbalance. It may not be a HUGE difference and it may not even be noticeable but it is enough to throw something out of wack. I say ride it down to the dealership, have them install a stage 1 air cleaner kit and remap it. You'll be glad you did. JMO

Hey, thanks for all the feedback. Sorry I didn't explain completely. Yes I plan on riding to the dealer and having them install the stage 1 and remap. But Mr. VETERAN75 brings up another point about an after market tuner. What is the TTS? Is it supported by Harley? Please explain or post link if it has already been disscussed on this fantastic forum. Thanks

Here's the OP - I don't see the words HAS TO anywhere...
So I don't think the guy is an idiot at all...his advice is certainly more conservative then yours but, as suggested in another post, you're not the one providing warranty coverage.
Dealer tells me not to ride my bike at all after installing new Vance and Hines slip ons without first remapping. Why not? Of course if the bike is pinging terribly or otherwise running bad I wouldnt. Im thinking I could at least ride to the dealer 80 miles away. Please correct me if Im wrong. Thanks
Wolfe,
The guys an idiot for telling him that he HAS TO remap with JUST slip-ons and that's not true. Yeh it will be breathing differently no doubt but I also doubt he'll NEED TO remap.

OF COURSE IT WILL! MINE DOES...
