FAQ — Hi-Output Holligan Exhaust
+ What does this exhaust fit? This looks like a Harley-style product, but the Fitment tab shows a Honda.
Correct — despite the generic Harley-style spec template on this listing, the Fitment tab confirms this exhaust is built for the Honda Grom, not a Harley-Davidson model. Fitment covers the Honda Grom 125 (2017-2020) and Grom 125 ABS (2018-2020). Use the Fitment tab above or the Ride Finder at the top of the page to confirm your exact model/year before ordering, and ask us using the chat widget on this page if anything looks off.
+ How loud is the Hi-Output Holligan 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. 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.
+ What's included in the box?
This is a complete Hi-Output Holligan system in brushed 304 stainless steel, with a CNC-machined billet end cap, a chambered high-flow catalyst cartridge, and a laser-engraved logo badge. It's 49-state emissions compliant.
+ Is there a Vance & Hines fuel tuner that fits this exhaust?
No — Vance & Hines' Fuelpak tuning modules (66045, 66043) are Harley-Davidson/Indian-platform products and don't cover the Honda Grom. Ask us using the chat widget on this page if you're looking for a Grom-compatible tuning option.
