Harley-Davidson and Indian Bagger Zombie Ring Inserts With Torque Cones
TAB Performance Zombie Rings – Aluminum Tip Inserts for TAB Slip-On Mufflers
PLEASE NOTE: Each purchase includes one complete set (2 pieces) of Zombie Rings in the size of your choice. These rings are engineered exclusively for TAB Performance aluminum tips on TAB Performance mufflers.
They will not fit steel tips.
➡️ Design Note:
-
The 3.5" Zombie Ring has a unique design variation featuring a star-shaped center with a “Z” logo—see the product thumbnails for reference.
-
For 4" and 4.5" mufflers using extensions, the torque cone may not reach as far into the baffle, which can alter performance results.
⚙️ Torque Cone Option:
The Torque Cone version is now integrated into the Z-Ring itself and cannot be added later. Be sure to select this option at checkout if you want it included.
Key Benefits
1. Performance Enhancement
-
Adds exhaust restriction for optimized back pressure and smoother power delivery without sacrificing sound.
-
Ideal for wide-open systems that require additional restriction to improve low-end torque and throttle response.
-
Systems already equipped with a catalyst may experience different results.
-
Some setups may show slightly lower peak torque on a dyno but deliver more consistent power across the range.
-
The ring alone provides mild restriction for appearance; the additional insert delivers the main performance impact.
2. Cosmetic Appeal
-
Adds a custom performance look inside the muffler cap.
-
Instantly sets your ride apart with precision-machined aluminum styling.
Sound Note
Zombie Rings will slightly alter the exhaust tone, especially during deceleration.
This is a fine-tuning component, not intended for major sound changes—it shifts the exhaust note deeper into the lower register.
Some riders love the enhanced tone and throttle smoothness, while others prefer the original Zombie setup. Because this is a tuning product, returns are not accepted if you dislike the sound change.
Finish Options
-
Bright machined aluminum finish
-
Can be painted or powder-coated with high-temperature finishes for custom style
-
Expect normal discoloration and carbon buildup over time, as these components directly interact with exhaust gases
