Vance & Hines does not publish an official decibel rating for this exhaust, so we won't guess a number here. It's a full 2-into-2 aftermarket system, so expect a noticeably louder, deeper exhaust note than stock. This system is not compatible with the Vance & Hines Quiet Baffle 23081, so there's no way to dial the volume back down after installing it — if a quieter note matters to you, ask us using the chat widget on this page before ordering. If you're subject to a local sound-ordinance limit, check your state/local regulations as well, 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.

This is a complete Big Radius 2-into-2 system — black-finished head pipes, mufflers, full-coverage heat shields, mounting hardware, and installation instructions are all included. No separate hardware purchase is needed to bolt it on for most fitting models — see the note below about the Low Rider ST and Heritage Classic 114, which need one additional part.

Yes, fitment is year- and model-specific. This exhaust fits 14 Harley-Davidson Softail models: FLDE Deluxe 107 (2018-2020), FLHCS Heritage Classic 114 (2023-2024), FLI Hydra-Glide Revival (2024), FLSL Softail Slim 107 (2018-2021), FXBB/Softail Street Bob FXBB 107 (2018-2020, plus 2022), FXBBS Street Bob 114 (2021-2024), FXFB Fat Bob 107 (2018-2019), FXFBS Fat Bob 114 (2018-2021, 2023), FXLR Low Rider 107 (2018-2020), FXLRS Low Rider S 114 (2020-2021), FXLRS Low Rider S 117 (2022-2024), FXLRST Low Rider ST 117 (2022-2024), and FXST Softail Standard 107 (2020-2024). It will NOT fit the '18-'22 Fat Boy, Breakout, or Low Rider ST models built before this fitment range — those are covered by a different Big Radius SKU. Use the Fitment tab above or set your bike in the Ride Finder at the top of the page and we'll confirm the exact match before you order.

Yes — Vance & Hines notes that the FXLRST Low Rider ST and FLHCS Heritage Classic 114 need a saddlebag support bracket kit (Vance & Hines part #1861-1250) in addition to this exhaust, sold separately. We don't currently carry that bracket kit in our catalog, so if you're installing on one of these two models, source that part before you start the install, or ask us using the chat widget on this page and we'll help you track it down. This system also has a tight clearance to the cam cover (.092" at its closest point, .250" minimum spec), so double-check header routing during install, and it's not compatible with the Vance & Hines Quiet Baffle 23081.
