Tab Performance
TAB Performance 50 Cals use a 4.5-inch muffler body that expands to a massive 5-inch outlet. Choose your model year first, then select the tip and baffle combination that matches how loud you want the bike.
The 50 Cal creates the oversized look and deep tonal foundation. Your baffle selection determines the final volume, throttle bark, and long-distance character.
The stronger all-around choice for riders who want a deep, muscular exhaust note without choosing TAB’s maximum-volume configuration.
Built for riders who want the loudest and most aggressive version of the 50 Cal. This is the maximum-presence option.
If the rest of the motorcycle remains in its factory configuration, the 50 Cals can generally be installed and ridden without immediately adding a tuner.
A tune becomes more valuable when the mufflers are combined with a freer-flowing intake, replacement head pipe, cam, or other engine changes. At that point, tuning helps match fueling to the complete combination.
Install the mufflers, choose the sound you want, and upgrade the rest of the system later if desired.
Once airflow changes on both sides of the engine, proper tuning helps deliver the best response and overall performance.
No cutting or welding is normally required. TAB states that the mufflers install with basic hand tools.
The listed price is for two mufflers with the selected tips and baffles.
Tips can be rotated in 90-degree increments to change their final position and appearance.
TAB Performance backs its mufflers with its manufacturer limited lifetime warranty.

The 50 Cal slip-ons aren’t subtle — and that’s the point.
With a massive 5" muffler body, these are built for riders who want their bagger to sound as big as it looks: deep at idle, angry when you crack the throttle, and still smooth enough to live with on real miles.
Whether you’re on a Twin Cam classic or a Milwaukee-Eight, the 50 Cals give you:
This is the slip-on for riders who want presence the second the bike fires up.
