FAQ — 2-into-1 Upsweep Exhaust
+ How loud is the Upsweep exhaust — is there a decibel rating?
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-1 aftermarket system with a megaphone-style muffler, 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, since we can't confirm a dB figure to compare against.
+ Does this exhaust increase horsepower?
Vance & Hines states the PCX™ (Power Chamber Exhaust) technology and chambered high-flow catalyst cartridge are designed to increase torque. 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.
+ What's included in the box?
This is a complete 2-into-1 Upsweep system — black-finished 304 stainless steel construction, megaphone-style muffler, mounting hardware, and installation instructions are all included. No separate hardware purchase is needed to bolt it on.
+ Does this need any extra clearance work to install?
Vance & Hines notes the header contacts the cam cover on this system, with a minimum clearance of .250” — worth knowing before you install so you can check clearance on your specific engine setup. If you're unsure whether this affects your bike, ask us using the chat widget on this page.
+ Will this fit my Fat Boy, Breakout, or Low Rider ST?
No — Vance & Hines specifies this system will NOT fit 2018-2022 Softail Fat Boy, Breakout, or Low Rider ST models, even though those are Softail-platform bikes from the same years as models this exhaust does cover. Fitment is model-specific, not just platform-specific — see the full list below.
+ Will this fit my Softail — do the years matter?
Yes, fitment is year- and model-specific. This exhaust fits 11 Harley-Davidson Softail models spanning 2018-2024, including the Softail Deluxe, Softail Slim, Street Bob, Fat Bob, Low Rider, Low Rider S, and Softail Standard, with the exact years covered varying by model. 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.
