I tend to value the opinions on this forum a bit more than those of my local HD shop. When I purchased my 09 Ultra Classic I had them install the Rinehart Slip-Ons, SE Stage-1 Kit and the SE Pro Super Tuner. They used a generic map, as the local shop did not have a Dyno. After a couple of months I noticed the some discoloration in the bend in my pipes and inquired with the local shop’s sister shop down the road. They stated it was too lean and needed to be Dyno’d, which I had them do. After a year, I wasn’t happy with the sound so I had a set of Power Master Slip-Ons installed at a bike rally. The PM Slip-Ons have a 2-1/4” baffle. I was told that I wouldn’t need to have the bike remapped and that it would have to be re-Dyno’d etc. Is this enough information for anyone to advise if I’m OK to continue running as is or if I really do need to have it re-mapped since changing the Rineharts to these Power Master Slip-Ons? That was the only change. Sorry for such a long note.
