Need to Decat but warranty worries

I just purchased a 2019 Road Glide Special with the 114 motor. I'v put about 2000 miles on it so far and only problem was the oil transfer from transmission to primary. The dealer has installed the vent kit under warranty. The only change I have done to the drivetrain is a set of Rhinhart slip ons. The weather has been very warm for this time of year but the heat coming of the bike is unbearable. I think the answer would be to decat the headers but then I would need to install a tuner and that will void the warranty. Don't know if I can wait the two years until out of warranty?

If you do decide to decat the header, you can purchase a oem decatted header from the auction site pretty reasonable price. This way you can keep your header for just in case. Others may know more than I, but the ox sensors are before the cat and if your state does not have epa test for motorcycles, no issues there. Also, a Harley tech would have to have a reason to look under the bike to see a different weld on the exhaust pipe. Not sure if when a tech access the ecm, it has the ability to detect exhaust flow, etc. Yes, a tune would be good to do and a Harley tune keeps your warranty, but not the best tune out there.

I did all the above, HD tune, stage 1 and street cannons, it worked for me and I have not had any issues with the Harley dealer.

Like I mentioned, other will know more than I.

Pickup an OEM header and decat yourself. You don't have to cut and weld. I drilled one out, just took a couple of hours. That way you still have your stock header.
Then, get the SEPST.

You can always buy the engine fan. I hear they work well pulling the heat off the riders.

I'm Having the same problem, wife complaining about the heat coming up from exhaust. Is there another guard that can keep the heat away from the passenger, or am I better off changing the exhaust? I have the blacked out motor and like the looks.

I have the same complaint on my 2018 RGS. Warranty is my concern too, extra 2 yrs worth. While moving, place your right hand below the seat, the heat seems to be coming from the rear cylinder area out the right side, above the cat(negligible on the left side). Not sure how much decatting will improve this. With the cylinders growing in diameter with larger displacement engines, there's less open space. Looks like the coolflow fan accessory may be the most effective means to shed the heat away from rider/passenger.

I plan on installing the warranty friendly SE pro street tuner for performance gains and possibly slightly less heat from a richer mixture. The coolflow fan may be the my next upgrade after that. Along with diverting heat away from rider/passenger, it has to be pulling extra heat off the rear jug. Down side is it shuts off above 40mph.

Whatever choice you make, keep in mind the warranty implications. If you're going to tune, don't let the dealer do anything other than the HD approved Street Tuner (EPA compliant). If you gut the CAT, keep one completely stock head pipe in reserve in case you ever have a major power train warranty issue. Also, don't use any other AC except the Harley "Stage 1" AC variations. Basically, all HD EPA approved "performance" parts. The Rinehart mufflers shouldn't throw any flags, so you should be good there.

You don't need to use a SE A/C. Any quality brand A/C will work and will not throw any flags against your warranty.

Wasn't speaking specifically of DT flags, speaking of the kind that the dealer might throw or what grenades the mother ship might throw if they start asking for descriptions, documentation, pictures etc.

He's already dropped the coin on the mufflers, so I figured they would be staying one way or another. In reality the stock M8 AC flows more than enough intake volume as is, but my dealer won't do a "Stage 1" tune without the slip ons and "upgraded" intake. Not sure it's worth risking an after market AC when there are a couple of approved options available.

That was my point.
