I’m very strongly considering changing out the stock decatted headpipe with a Jackpot before changing out my Vance and Hines turn downs to something else. My 2018 Vintage has a little over 5000 miles on it. Is it a problem to spray the nuts securing the head pipe with a penetrating oil? I’m concerned mainly on the rear head that all that heat even at 15 ftlbs of torque may be a pain to remove. I have a shop manual for it and I’ve done a head pipe replacement on my 14 HD Streetglide so I have some mechanical inclination. Also those of you who done this what did you do to get a good angle in the bottom rear headpipe bolt? And did you replace your gaskets?
