i bought my 48 a few months back and now looking to put v&h shortshots on it and the bike came with slip on mufflers that sound pretty good but i wanna up grade my bike also came with a aftermarket air cleaner i just wanted to know if it was already remapped because of the aftermarket air cleaner on it and the slip on mufflers im looking to order my new pipes here in the next week or so any input in appreciated

 

Does it pop at all when you let off the throttle? That's usually a good indicator that it hasn't been remapped.

 

Just the normal back pressure not a lot of popping
