Thanks. The tuner guys say the tuner doesn’t void the warranty but I’m guessing cutting the cat out does. I gotta cut the baffles out for the full sac anyway, I’ll start there and see how it performs before cutting the cat.
I got on the throttle last night with my lady and it sounded like a souped up Honda Civic. Ugggg
The "tuner guy" is wrong, running anything but the street legal and EPA approved calibrations on a 2017 and later Harley will void your powertrain warranty as soon as H-D detects it, and it is checked every time a dealership connects their equipment to your bike. IF you install a street legal performance kit from Harley and use their "Street" tuner to load a legal calibration, the warranty is preserved.
As for the catalytic converter, you're right, removing it is also an emissions violation that could be used to void your warranty. It's not something H-D can determine from just hooking up the dealership equipment to your bike however. If you want to go that route, you might want to seriously consider buying an aftermarket catless system and putting your stock head pipe assembly in storage. If your bike needs major engine work under warranty you could always swap the pipes before taking the bike to the dealer. Once you cut the cat from the stock system there is no going back unless you want to buy another stock system. Once you go catless, either way, you will need a tune. See the first paragraph for the implications of that. Research carefully, some systems claim they can put your ECM back to the legal tune and not leave a trace for Harley to detect but that may or may not be true in all cases. If these bikes were highly reliable and trouble free it might be worth taking a chance; but you can't say that about Harley's products.
