A Harley slip-on is a fitment-specific muffler replacement, not a universal pipe. The year, family, factory header arrangement, bag clearance and the kit’s left/right configuration matter before finish or sound. This list deliberately separates Touring, Softail, Sportster and Street applications rather than claiming that a pair fits every Harley. Sound and performance language below is sourced from manufacturers; local noise rules, emissions law and any inspection requirement still govern what can be used on the road.

The picks, in detail
Vance & Hines Eliminator 400 Slip-Ons
A pair of 4-inch round Touring mufflers with CNC-machined billet end caps, offered in black and chrome-based finishes. Vance & Hines lists specific 2009–2016 and 2017–2024 Touring applications by part number; select the exact part for the motorcycle rather than using the name as a blanket fitment.
- pair of 4-inch Touring slip-ons
- CNC-machined billet end caps
- optional quiet baffles
- Maker describes a deep, aggressive bagger exhaust note
- Some 2009–2016 applications are declared 50-state emissions-compliant replacements
- Later-model legality depends on the exact part and application
- Not a Softail, Sportster or Street fitment
Khrome Werks 4.0-Inch HP Plus Mufflers (2017-Current Touring)
A paired Touring-muffler family for 2017-current models, sold with black or chrome shells and straight-cut or slash-up tips. Choose the listed baffle configuration and tip rather than assuming the same part fits the prior Twin Cam Touring layout.
- pair for 2017-current Harley Touring
- 4-inch muffler bodies
- black or chrome, straight or slash-up finishes
- Several current finish/tip choices at the same platform
- $499.95 observed manufacturer price
- Fitment is Touring-only
- Ripper-baffle variants change sound character and should be chosen deliberately
Khrome Werks 4.5-Inch HP Plus Mufflers (2017-Current Touring)
These are the larger 4.5-inch paired HP Plus Touring mufflers, including the Obsidian shell with Tracer end cap. Khrome Werks describes an engineered baffle and a tunable-insert system intended to alter restriction and sound using hand tools.
- pair for Milwaukee-Eight Touring
- 4.5-inch 16-gauge bodies
- Tunable Muffler System inserts
- Manufacturer claims improved torque and horsepower response
- End-cap and baffle system gives more configuration than a fixed muffler
- Premium price compared with the 4-inch HP Plus pair
- Sound and emissions status must be checked for the precise part and jurisdiction
Khrome Werks 4.0-Inch HP Plus Mufflers (1999-2016 Touring / Trike)
The earlier-generation 4-inch HP Plus pair is expressly listed for 1999–2016 Touring models and all Trikes, with black or chrome and straight/slash choices. It is the correct-era alternative to the 2017-current M8 Touring product, not an interchangeable successor.
- pair for 1999–2016 Touring and Trike
- 4-inch bodies
- black or chrome and two tip profiles
- Keeps fitment aligned to the older Touring platform
- Same broad finish choice as the newer family
- Does not fit 2017-current Touring by this listing
- Confirm luggage and header compatibility on the exact motorcycle
Khrome Werks 3-Inch Tapered Sportster Mufflers (2014-2022)
A paired, chrome 3-inch tapered muffler option specifically listed for 2014–2022 Harley-Davidson Sportster models. It belongs on the Sportster branch of the shopping decision, not on a Touring or M8 Softail with a different exhaust layout.
- pair for 2014–2022 Sportster
- 3-inch tapered mufflers
- chrome finish
- Clear, narrow Sportster year range
- Smaller visual profile than 4-inch Touring cans
- No Touring or Softail compatibility
- Choose only after confirming the motorcycle is in the listed Sportster generation
Khrome Werks 3.5-Inch Shredder Mufflers for M8 Softail Staggered Duals
A paired Shredder set for 2018–2026 M8 Softails using staggered dual headers, offered in chrome or black. The header requirement is central: this is not a bolt-on answer for a Softail running a different 2-into-1 or shorty-dual arrangement.
- pair for 2018–2026 M8 Softail staggered duals
- 3.5-inch mufflers
- black or chrome finishes
- Specific current M8 Softail fitment
- Two finish choices
- Requires the stated staggered-dual header configuration
- Does not cover Heritage/Deluxe shorty-dual layouts
Khrome Werks 3.5-Inch Shredder Mufflers for FLHC/FLDE/FLI Shorty Duals
This separate paired Shredder set is for the FLHC, FLDE and FLI 2018–2024 Softail shorty-dual layout. Keeping it separate from the staggered-dual product prevents the common error of treating all M8 Softail muffler brackets as the same.
- pair for FLHC, FLDE and FLI 2018–2024
- 3.5-inch bodies
- black or chrome finishes
- Explicit shorty-dual fitment
- Addresses a distinct Softail exhaust layout
- Not for general 2018-up Softails
- Check the exact model code and original header arrangement
S&S Grand National Slip-Ons for M8 Touring Models
S&S sells this as a paired Grand National slip-on kit for M8 Touring in black or chrome. The black M8 Touring version is described as a 50-state legal emissions-replacement part for 2017–2021 FL Touring applications, which is a narrower statement than a universal legality claim.
- pair for M8 Touring
- black or chrome shells
- 4-inch Grand National format
- Specific 2017–2021 FL Touring emissions-replacement declaration for the black version
- Recognizable Grand National styling
- Confirm both year and finish-specific approval before purchase
- Not an M8 Softail product
S&S Grand National Slip-Ons for M8 Softail Models
The M8 Softail Grand National kit is a distinct paired product, available in black or chrome, with its own mounting and model-family fitment. Buy by the S&S application listing and bracket orientation; it is not the Touring Grand National kit moved to another motorcycle.
- pair for M8 Softail
- black or chrome versions
- Grand National muffler family
- Purpose-built M8 Softail alternative
- Two finish options
- Retail pricing is notably higher than the Touring version
- Softail submodel and header arrangement need confirmation
Rinehart 4-Inch Slip-Ons for Harley Street 500 / 750
Rinehart’s 4-inch pair is specifically made for 2015-later Harley-Davidson Street 500 and Street 750 motorcycles. It is a useful reminder that Street, Sportster, Softail and Touring are separate fitment families even when every product is marketed as a Harley slip-on.
- pair for 2015-later Street 500 and Street 750
- 4-inch mufflers
- Street-model application
- Exact model-family coverage instead of generic Harley language
- Rinehart product page provides a dedicated Street application
- Does not fit Touring, Sportster or Softail models
- Availability and local road-noise rules should be checked before ordering
Buying tips
- Start with VIN/year, exact model family and current headers. A slip-on attaches downstream of a compatible header; it does not correct a mismatched exhaust layout.
- Confirm whether the listing is a left-and-right pair, then check the instructions for clamps, mounts and any required hardware before removing the factory mufflers.
- A louder or freer-flowing exhaust is not automatically legal or tune-free. Use the manufacturer declaration for the exact part and follow local emissions and noise requirements.
