The short version: run one Zombie baffle and one Louvered baffle in your TAB slip-ons. You get a deeper tone than a pair of Louvered baffles, and it's not as loud as running two Zombies. It's the setup we recommend most to touring riders who want the bike to sound right without being too much.
What the dual baffle setup is
TAB slip-ons come with a matched pair of baffles. You pick one sound:
- Zombie baffles – TAB's loudest option.
- 2.5" Louvered baffles – TAB's middle option, more toned down.
The dual baffle setup puts one of each in your bike: a Zombie on one side and a Louvered on the other.
Why we recommend it
A lot of riders land in the same spot. Two Zombies sound great on a short blast, but they can be more than you want on a long day, at slow speeds, or rolling through town. Two Louvered baffles are easy to live with, but some riders feel they give up too much bark.
One of each splits the difference:
- A deeper tone than two Louvered baffles
- Not as loud as two Zombies
- Still has the bark when you roll on the throttle
- Calmer at slower speeds and around town
This is how Rocco runs his own 2018 Street Glide: TAB 2-1-2 header with 50 Cal slip-ons, a Louvered baffle on the right side and a Zombie on the left. It keeps the deep bark without making the bike overly loud at slower speeds. If you can't decide between the two baffles, this is the one we'd point you to.
What it costs
Pick 1 Louvered + 1 Zombie under Baffle Selection on the product page.
- TAB 50 Cal 5" slip-ons: +$90 ($989.95 vs. $899.95 with a single baffle type)
- TAB 4.5" B.A.M. Stick slip-ons: +$70 over the single baffle price of the finish you pick
Free shipping. Everything we sell ships free except RickRak.
Why not just buy a second baffle set from TAB?
TAB doesn't sell a Zombie + Louvered combo as a set. Their replacement baffles come as a pair of the same type. To get this setup on your own, you'd buy your slip-ons, then buy a second baffle set:
- TAB 5" (50 Cal) replacement baffle set: $129.95
- TAB 4.5" replacement baffle set: $119.95
Our +$90 on the 5" saves you about $40, and our +$70 on the 4.5" saves you about $50, before TAB's shipping on the baffle set. You also don't end up with two extra baffles sitting in the garage.

4.5" and 5" baffles are different parts
The 4.5" baffles and the 5" baffles are not interchangeable. A 5" baffle only fits 5" (50 Cal) mufflers, and a 4.5" baffle only fits 4.5" B.A.M. Stick mufflers. TAB uses different part numbers for each:
- 5" (50 Cal): Zombie 122-0525, 2.5" Louvered 122-2505
- 4.5": Zombie 122-0225, 2.5" Louvered 122-2503
When you order the dual baffle setup on one of the pipes below, we match the baffles to the pipe for you.
