2024 Heritage classic 114 question
I just bought a new heritage for my wife to ride. She wants to put tab slip ons with zombie baffles on it. My question is to people who have done this, do I need to have the bike tuned or anything with this modification? When I installed cobra neighbor haters on her softail slim(103), I was told I could install those slip ons with no further modifications, from the dealer where I bought them, several forums, and a couple of friends who have been riding/wrenching for a long time. That bike always made popping noises when decelerating. It was annoying and I'd like to avoid that, if possible. I was told the reason for the popping noises was when I removed the stock slip ons from the slim and installed the cobra slip-ons, I also removed the catalytic converters. I was told that a tune may/may not have fixed that. Any help?

Harley will certainly recommend a tuner. Three years ago when my wife purchased her new 21 Heritage, they insisted on it. She got V&H with no other mods and they sound simply awesome.
I purchased a used 19 Heritage from the same dealer a year later. I didn't even think to ask about a tuner. I found out later my bike never had one. I had it checked out by another dealer (long story and for other reasons) and it's fine. However, they did say I should have it tuned but "it's good for now" My point is with just slip-ons and no other mods, I don't believe a tuner is essential. But at the same time I think it's a good idea.
That said with TABs and zombies, I would. I just would.

Go to DK Customs site. They have a video that explains why the M8s do not need a tuner like the TC did, add a cam the M8 definitely needs a tuner. M8 has more self adjustment to the fuel air ratio then the TC had stock.
I trust DK Customs for advice, watch the video.

Any time you do an exhaust mod that results in backfiring on decel, a tune will likely clear it up. If you have no popping with the slip-on's on her new M8, you're good to go.

Thanks for the input everyone. I searched through DK Customs website, and youtube channel(for hours, a lot of great information on these) last night hoping to find the video(s) mentioned above here but I couldn't find this particular one:

Anyone have a link to this?
