I’d leave the baffles out all together and install the large TTI’s from DK. Just don’t get on the throttle through residential areas at night. A stock 80 is a great little motor and with a stock cam it’s really not that loud…. If it is you can always slide them un-wrapped back in. You can also cutt them down, try taking 3-4 inches off their length if you wanna control how much more motor you wanna hear.
Those TTI’s will rid you of reversion issues and deepen the tone.
I’ll quickly address the comment above.. I’ve ran big stroked high compression motors with wide open pipes going on 35 years.. I have never once had anyone complain, nor have I ever gotten pulled over, not even in Daytona bike week for noise. Not everybody who reduces back pressure and enjoys a more aggressive sound sits around all South Park at every light. I like to balance enjoying the sound while being cognitive of others feelings. With out a bunch of throttle twisting it’s just not a big deal. We can stand United against the loud radios… I hate that with the burning heat of a thousand suns.
I can respect those who want silence but it’s not fair to assume those with more aggressively sounding bikes are obnoxious.
OP, awesome bike. I really like the Bad Boys.. to me they are the Shelby of the mustangs that one day will be highly sought after and the dream of every collector.

Awesome analysis, R2m. I get everything you are saying, and most of my bikes have aftermarket mufflers for that reason. But removing the packing from the baffles wouldn't improve performance any, just make it louder. Right?

Performance on a 80 inch stock.. no. On a 80 inch with higher compression bigger cam maybe.. on a big motor, especially a cam with more overlap.. defiantly yes.
Your 10:1 with EV46 and mildly ported heads… I bet the wadding removed would improve it.. more air would get out faster.. removing the baffle all together would in my opinion go like this.. no baffle with RTI’s a little more power up top, maybe the same or a tiny bit less down low. Half a baffle with TTI.. probably the same bottom, a little more up top
And actually free flowing stock headers with very large capacity free flowing mufflers like cycle shacks are an awesome awesome street solution. Fast, good sounding and on the quiet side for those who enjoy that more.
Drag pipes got a bad name because everyone installed them on anemic stock motors and then had a bunch of reversion and they couldn’t tune it right. Drag pipes are only appropriate when there is more compression, cubes, rpm… but if you tune them.. (equal length, and a length and diameter specific to your cam… they are just about unbeatable. The two into one guys will argue but most of them are of that opinion because they didn’t tune the drag pipes when they tried them… or worse their Dyno guy just told them all drag pipes suck because they spend all their time behind a dyno and don’t ever really race anything. They don’t learn to tune the bike for “faster” they tune for paper numbers and think it’s the same. 2 into 1’s can be very good as well. Especially for a 80inch hoped up motor that is exactly what 90% of them were designed and tuned for. When you go bigger they can really choke big motors, just not designed for that many inches.. especially above 98”

Nice score. Same color as my 96 BB. I agree on the black headlight but also that it needs to be put back up in the original spot. Sorry I can't help with bracketry for that. I do have the parts book tbiugh if you need help with part numbers. Looks to have a bunch of chrome covers everywhere that I don't care for but they're easily removed if you dont like them. How many miles?
If you decide you don’t want the starter to oil tank / tranny to motor chrome plates I’ll buy em from you.
When I was a diehard Shovel chopper guy I made fun of these new EVO and Twink dentist/doctor bikes with bolt on nonsense (real men made their parts) now I’m 54 and love that period correct stuff.. looks cool and you can’t buy it new anymore. I wonder if in 25-30 more years I’ll think S&S air covers on fuel bikes will be cool…. Nay.
Anybody see that morris Magneto came out with a nose cone for the M8?… meaning you can now go carb and yank out every single bit of wiring harness and Ecu from a new M8 style bike! I’m excited… just might buy one and strip that puppy down to just being a motorcycle!

45k miles. Yeah I'm thinking of taking those chrome covers off as well.
I do like my bikes to be fairly loud, but I don't go around revving and being annoying. I have 42 inch true dual fishtails with no baffles on my 97 heritage, and they aren't overly loud at all to me.
We're drifting the OPs thread, but don't forget drag pipes and tuned exhaust are tuned for specific RPM, usually for top performance on a drag strip. Adding a muffler, and a crossover, flattens the curve and makes the bike more enjoyable on the street. That's also where they say 2-1 pipes shine, more torque for street riding. I'm considering a set for my Heritage, to see if that's true.
Sorry @bulldog1776 for the drift. You have a nice bike, enjoy it.
While that ignition pickup is the stock style, it looks like the Standard Motor Products replacement. The original would have had the components potted under a brown silicone looking material that turns to goo over time.
