Best Exhaust For Low Rider St: Choosing a Softail-Compatible Setup

#1 · Best Overall

1. YANGSHIZI LAF Pipes

• Material: Alloy Steel
• Material Type: Alloy Steel
• Compatible with Vehicle Type: Motorcycle

Best for: Downswept custom Harley pipes.

Why it ranks #1: Its stated fitment includes Softail models through 2025, with 2-inch pipes, flange kits, and O2 adapters; gaskets and mufflers are separate.

A Y-shaped, downswept layout is the defining feature of these black 2-inch LAF pipes, with the listing saying the shape avoids the transmission case for a low stance. A built-in 18mm O2 port and included 12mm adapter support sensor connection options across specified Harley families.

The dual-pipe setup includes flange kits and O2 adapters, pairing the 2-inch pipes with hardware for the listed mounting and sensor connections. The 18mm port and 12mm adapter offer two stated sensor sizes, while direct-bolt-on installation and flexible DIY mounting are described in the listing. The claimed downswept clearance around the transmission case is relevant to a low custom stance. Gaskets and mufflers are sold separately, so this is not a complete exhaust package.

Skip it if you want a complete exhaust with gaskets and mufflers included; the S&S Cycle MK45 listing describes mufflers rather than this pipe-only package.

These suit a custom Harley build seeking downswept black pipes and the listed O2 adapter arrangement. Check the exact motorcycle and mounting needs against the stated fitment; plan separately for gaskets and mufflers to complete the system.

#2 · Forward-Control Fit

2. mhanewv LAF Pipes

Best for: Forward-control LAF pipe builds.

Why it ranks #2: The listed coverage includes Softail models and the kit supplies flange kits and O2 adapters, but it is only for forward-control bikes.

A built-in 18mm O2 sensor port with a supplied 12mm adapter gives these black 2-inch LAF pipes options for sensor connections. Their stated coverage includes 1984–2023 Softails and specified Sportster and Dyna models, making control layout a key fit check before planning an installation.

The listed 2-inch pipes come with flange kits and O2 adapters, so the package supplies those connection pieces for the intended exhaust setup. The 18mm port and 12mm adapter accommodate the stated sensor sizes, while the broad model range covers selected Softail, Sportster, and Dyna motorcycles. Fit is limited to forward-control configurations; mid-mounted footpegs are explicitly excluded. Gaskets and mufflers are sold separately, and some Dyna or Touring models may require modifications or adjustment.

Skip it if you have mid-mounted controls, since the pipes are specified for forward-control models; the FatFlex 36 Inch Fishtail fits listed Touring models instead.

Consider these for a forward-control Harley project within the listed Softail, Sportster, or Dyna ranges, especially when the O2 adapter is useful. Confirm the exact model and control layout; gaskets and mufflers are not included.

#3 · Stainless Baffle

3. S&S MK45 Mufflers

• Material: Stainless Steel
• Material Type: Stainless Steel
• Compatible with Vehicle Type: Tractor

Best for: Tracer-tip muffler upgrade.

Why it ranks #3: These 4.5-inch mufflers have stainless-steel baffle construction, but the supplied details do not establish Low Rider ST or Softail fitment.

A black Tracer end cap sets these 4.5-inch S&S Cycle MK45 mufflers apart, giving buyers a defined tip style alongside a choice of show-quality chrome or Jet-Hot black ceramic finish. Stainless-steel baffles and fiberglass packing are specified, with a listed seven-horsepower gain for riders considering a muffler-focused upgrade.

The 4.5-inch muffler format and Tracer end caps offer a more specific alternative to a plain-ended exhaust, while the finish choice lets buyers coordinate the visible hardware with their motorcycle. Stainless-steel baffle construction and fiberglass packing are the stated internal materials; S&S also lists a seven-horsepower gain. The separate stainless-steel quiet-baffle kit matters for buyers considering sound control, since it is not included in the listed mufflers. Check local noise and emissions rules before ordering.

Skip it if you need a quiet-baffle kit included with the mufflers, since S&S lists that kit as a separate purchase.

Choose these for a muffler-focused project where the 4.5-inch profile, Tracer caps, and finish options suit the bike. The listing does not establish a Low Rider ST fitment, so check fit and local compliance before ordering.

#4 · Large Round Mufflers

4. Vance & Hines 450 Slip-Ons

• Material: Metal
• Material Type: Metal
• Compatible with Vehicle Type: Motorcycle

Best for: Matte-black stretched-bag fit.

Why it ranks #4: Its 4.5-inch mufflers and LS275 baffle are specified for Touring models, not the Low Rider ST, so confirm fitment before considering it.

Flush outlets align with stretched saddlebag cutouts, giving the Vance & Hines 450 slip-ons a specific fit-oriented detail for Touring bikes. Their 4.5-inch round mufflers carry a matte-black finish, and the patented LS275 baffle is specified for sound and power performance.

The flush outlet position is intended to match stretched saddlebag cutouts and follow the rear angle of the bags, making that bodywork an important fit consideration. Large 4.5-inch round mufflers give the system its stated profile, while the LS275 baffle is the named internal feature. Vance & Hines lists fitment for 2017–2023 Harley-Davidson Touring models and 50-state emissions compliance; the replacement-part note specifies 2017–2022 models, so check the relevant model year carefully.

Skip it if you ride a 2009–2016 Touring model; SHARKROAD's 36 Inch Fishtail is listed for that earlier Touring range.

A fit-oriented option for 2017–2023 Touring owners with stretched saddlebag cutouts who want matte-black 4.5-inch mufflers. Because the replacement-part note ends at 2022, verify the relevant year and bag-cutout layout before choosing.

5. FatFlex Fishtail Mufflers

• Material: Alloy Steel
• Material Type: Alloy Steel
• Compatible with Vehicle Type: Motorcycle

Best for: Matte-black Touring fishtails.

Why it ranks #5: The 36-inch black slip-ons are listed for 2017-and-newer Touring models, making them a poor documented fit for a Low Rider ST.

The 36-inch shark-fin fishtail tip gives these FatFlex slip-on mufflers a distinctive rear profile, while the matte-black finish keeps the visible surface dark. They are listed for Harley 2017-and-newer Touring models, and the slip-on format uses the existing exhaust removal and bolt-tightening workflow.

For a listed Touring bike, installation involves loosening the bolts, removing the stock exhaust, slipping on the new muffler, and tightening the bolts; the supplied bolts and nuts support that process. The 36-inch length, 1-7/8-inch body diameter, and specified inlet diameters help buyers assess the physical setup. FatFlex says retuning is generally not required after installation, but notes that tuning may be needed. Each unit is individually inspected before packing, according to the listing.

Skip it if you ride a 2009–2016 Touring model; the SHARKROAD 36 Inch Fishtail is listed for that year range.

A practical match for owners of listed 2017-and-newer Harley Touring models who want a long, matte-black fishtail slip-on. Check the stated inlet dimensions against the bike, and allow for tuning if the installation calls for it.

6. SHARKROAD Fishtail Exhaust

• Material: Metal
• Material Type: Metal
• Compatible with Vehicle Type: Motorcycle

Best for: Chrome 2009–2016 Touring fit.

Why it ranks #6: This chrome 36-inch slip-on is explicitly listed for 2009–2016 Touring models, outside the Low Rider ST’s stated Softail application.

A triple-layered polished-chrome surface gives the SHARKROAD 36-inch fishtails a bright finish, with a slip-on layout for listed 2009–2016 Harley Touring motorcycles. Both inlets have a stated 1-3/4-inch inner diameter, helping buyers evaluate the connection dimensions before installation.

The slip-on workflow is straightforward in the listing: loosen the bolts, remove the old muffler, fit the fishtail, and tighten the bolts. That approach makes these a muffler replacement rather than a complete exhaust system. Their 36-inch length and 1-7/8-inch body diameter are useful checks for available space, while matching 1-3/4-inch inlets define the connection size. The stated fitment covers Touring models from 2009 through 2016, including examples such as Road Glide and Road King.

Skip it if you own a 2017-or-newer Touring model; the FatFlex 36 Inch Fishtail is listed for 2017-and-newer Touring bikes.

Choose these for a listed 2009–2016 Touring motorcycle when chrome fishtails and a slip-on replacement suit the project. The 36-inch length and equal inlet dimensions are important fit checks before removing the existing mufflers.

7. Patriot Shielded Side Pipe

Best for: Long shielded side-pipe builds.

Why it ranks #7: The 60-inch side-pipe kit has a 3-inch outlet, but its supplied details do not identify motorcycle or Low Rider ST compatibility.

A 60-inch shielded side-pipe layout with full 360-degree rotation at both inlet and outlet gives this Patriot kit installation flexibility. Its show-quality chrome finish and slash-cut 3-inch outlet define the visible style, while the louvered-core mufflers are specified for low-back-pressure performance.

The full rotation at both ends lets installers orient the inlet and outlet to suit the exhaust layout, while the bolt-on installation type provides the stated mounting approach. A slip-fit inlet measuring 2 to 2.5 inches accommodates a range of factory and aftermarket exhaust connections, and the 3-inch slash-cut outlet sets the exit size. Six-sided louvered-core mufflers pair with the large pipes for the stated low-back-pressure design. At 60 inches, this is a long side-exhaust format.

Skip it if you need a compact motorcycle slip-on rather than a 60-inch side-pipe system; the FatFlex 36 Inch Fishtail is listed for Harley Touring models.

Consider this for a vehicle project suited to a long shielded side-pipe layout, adjustable end orientation, and a chrome finish. Its 60-inch length and 2-to-2.5-inch slip-fit inlet make connection space and routing key considerations.
