Vance & Hines does not publish an official decibel rating for this exhaust, so we won't guess a number here. It's a full aftermarket system (not a quiet baffled slip-on), so expect a noticeably louder, deeper exhaust note than stock. If you're subject to a local sound-ordinance limit, check your state/local regulations before installing, since we can't confirm a dB figure to compare against.

Vance & Hines states the PCX™ (Power Chamber Exhaust) technology and chambered high-flow catalyst cartridge are designed to increase torque as you accelerate through the gears. The brand doesn't publish a specific horsepower or torque number for this system, so we won't quote one here — if exact dyno figures matter to your decision, ask us using the chat widget on this page and we'll help track down what's available.

A full exhaust system like this changes airflow enough that many riders choose to re-tune the fuel map for a cleaner idle and throttle response — see the Fuelpak tuners linked above, both confirmed compatible with this exhaust's fitment. It's not a strict requirement to ride the bike, but skipping it can mean a slightly leaner or richer stock fuel map than the exhaust was designed around.

This is a complete Shortshots Staggered system — chrome head pipes, staggered dual mufflers, full-coverage heat shields, mounting hardware, and installation instructions are all included. No separate hardware purchase is needed to bolt it on.

Yes, fitment is year- and model-specific. This exhaust fits FLFB Fat Boy 107 (2018-2019), FLFBS Fat Boy 114 (2018-2022), FXBR Breakout 107 (2018-2019), FXBRS Breakout 114 (2018-2020), and FXDRS FXDR 114 (2019-2020). If you're also adding a tuner, we've matched two above: the Fuelpak X covers every model here through 2020, and the Fuelpak 4 (M8/Pan America) covers the newer 2021-2022 Fat Boy 114 years the Fuelpak X doesn't reach. Set your bike in the Ride Finder at the top of the page and we'll confirm the exact match before you order.
