Best Exhaust For Ninja 650: Compare Full Systems and Slip-Ons

#1 · Best Overall

1. Generic Ninja 650 Full System

Best for: Ninja 650 replacement buyers.

Why it ranks #1: Its full-system listing explicitly covers Ninja 650 and Z650 models from 2017–2022 and specifies stainless steel construction.

A stainless-steel full exhaust system is the defining feature of this Ninja 650 and Z650 replacement kit, giving owners a listed option for replacing an old or damaged exhaust. Its stated 2017–2022 application helps narrow the choice to riders shopping within those model years.

The listing identifies a full exhaust pipe set for Ninja 650 and Z650 motorcycles from 2017 through 2022, so it targets a specific model-year range rather than a universal slip-on. Stainless-steel construction is described as offering lasting performance in varied weather, while the smooth, glossy finish comes from its stated craftsmanship. Those details suit a buyer seeking a replacement with a finished appearance, though the listing provides little installation guidance beyond describing it as a replacement for an old or damaged pipe.

Skip it if you need a slip-on muffler or detailed installation dimensions; this listing describes a full replacement pipe set instead.

This suits a Ninja 650 or Z650 owner seeking a stainless-steel full replacement for a damaged exhaust within the listed 2017–2022 range. Treat the year range as the stated fitment boundary; installation details are limited.

#2 · Broadest Model Range

2. Generic 650 Full System

• Weight: 1.76 oz

Best for: Full-system airflow seekers.

Why it ranks #2: The full-system listing names Ninja 650 among several Kawasaki models and states fitment from 2012–2022.

An airflow-focused full system with a sliding mid-section connector is the key draw for riders considering a broader exhaust change. The listing says the system is intended to improve airflow and amplify the motorcycle’s natural exhaust note, and names Ninja 650 among several Kawasaki applications spanning 2012–2022.

The stated airflow improvement is intended to increase horsepower and torque, giving this system a performance-oriented purpose beyond replacing a muffler. Its sliding mid-section connector is described as making an upgrade easier for riders of different skill levels, while the fuller, deeper exhaust note targets buyers seeking a change in sound. Listed applications include Ninja 650, Z650, ER6N, ER6F, and Versys 650 for 2012–2022, so compatibility remains tied to those models and years.

Skip it if you need a stated inlet measurement before choosing; the KJTYSDM Ninja 650 slip-on listings specify 51 mm or 60 mm options.

This fits a rider seeking a full-system change, a sliding connector, and a deeper exhaust note across the listed Kawasaki models. Check that the motorcycle falls within the stated applications and 2012–2022 range.

#3 · 51mm Inlet Option

3. KJTYSDM Ninja 650 51mm Slip-On

• Weight: 2.2 lb

Best for: 51 mm Ninja 650 slip-on.

Why it ranks #3: This slip-on names the Ninja 650 and specifies a 51 mm inlet, stainless steel construction, and a compact 310 mm overall length.

The specified 51 mm inlet makes this KJTYSDM slip-on the clearly identified option for a Ninja 650 buyer whose mid-pipe measures to match. Its listing combines that single inlet size with stainless-steel construction, a heat-resistant carbon-fiber pattern, and a compact angled-outlet form.

Unlike listings offering two inlet variations, this version specifies a 51 mm inlet, so measuring the connecting or mid-pipe is central to choosing it. The supplied fitment guidance also calls for checking bracket position, installation angle, swingarm clearance, and distance from the tire and bodywork. Stainless steel is used for the muffler, and the stated approximate 310 mm length, 195 mm body, and 140 mm angled outlet give buyers useful dimensions for assessing the available space.

Skip it if you measure a 60 mm mid-pipe; the KJTYSDM Ninja 650 60 mm-option listing offers that inlet size instead.

This suits a Ninja 650 owner whose measured connecting pipe matches the listed 51 mm inlet and who wants a compact slip-on. Verify the bracket, angle, and surrounding clearances before choosing it.

#4 · Broad Year Coverage

4. KJTYSDM Ninja 650 Slip-On

• Weight: 2.2 lb

Best for: Broad-year Ninja 650 slip-on.

Why it ranks #4: Its listing states Ninja 650 fitment from 2007–2024 and offers 51 mm or 60 mm inlet options to check against the mid-pipe.

A stated Ninja 650 fitment range of 2007–2024 sets this slip-on apart from listings with narrower year coverage. It offers 51 mm or 60 mm inlet choices, plus stainless-steel construction and a heat-resistant carbon-fiber pattern, for a buyer who can verify the mounting dimensions.

The two inlet options require measuring the outside diameter of the motorcycle’s connecting or mid-pipe where the muffler mounts. That measurement, along with the listed checks for bracket position, installation angle, swingarm clearance, and tire and bodywork distance, helps determine whether the slip-on suits the actual exhaust layout. Its approximate 310 mm length, 195 mm body, and angled 140 mm outlet describe a compact assembly, while the stated 2007–2024 Ninja 650 range identifies the intended model application.

Skip it if you want a full exhaust system rather than a slip-on muffler; the generic 2012–2022 listing describes a full system for several Kawasaki models.

This is for Ninja 650 owners shopping within the stated 2007–2024 range who want a compact slip-on. Confirm the inlet diameter and inspect bracket position and nearby clearances before selecting an inlet option.

5. KJTYSDM Multi-Model Slip-On

• Weight: 2.2 lb

Best for: Multi-model slip-on shoppers.

Why it ranks #5: It names the Ninja 650 alongside other motorcycles and offers 51 mm or 60 mm inlets, but does not give a Ninja-specific year range.

Two selectable inlet sizes—51 mm or 60 mm—make this compact slip-on a measurement-led choice for compatible motorcycles. The listing names Ninja 650, 650R, ZX6R, and ZX10R, and pairs a stainless-steel muffler with a heat-resistant carbon-fiber pattern for its exterior appearance.

The 51 mm and 60 mm inlet choices let a buyer match the muffler to the outside diameter of the connecting or mid-pipe at the mounting point. The listing also calls for checking bracket position, installation angle, swingarm clearance, and distance from the tire and bodywork, making physical clearance part of the selection process. At approximately 310 mm long, with a 195 mm body and angled 140 mm outlet, its compact slip-on format is distinct from a full-system replacement.

Skip it if you cannot measure your mid-pipe or verify mounting and clearance; the QWRXDGS listing is a full-system alternative, though its fit details are sparse.

Choose this for a Ninja 650 or another named model when a compact slip-on suits the project and its inlet size matches. Measure the pipe and assess bracket location, angle, swingarm, tire, and bodywork clearance.

6. Generic 650 Sliding Full System

• Weight: 1.76 oz

Best for: Multi-Kawasaki full-system buyers.

Why it ranks #6: This stainless-steel full system names Ninja 650 and related Kawasaki models for 2012–2022, but its listing does not provide detailed dimensions.

A sliding mid-section connector anchors this full-system listing, which names Ninja 650 alongside ER6N, ER6F, Z650, and Versys 650 for 2012–2022. The stated airflow aim and deeper exhaust note give it a different focus from a compact, inlet-sized slip-on muffler.

The listing says improved airflow is intended to increase horsepower and torque, while its sliding connector is described as easing the upgrade process. It also targets riders who want a deeper, fuller exhaust note rather than only a replacement part. Stainless steel is specified in the additional description, and the named Kawasaki applications and 2012–2022 range help define the intended fitment; however, no inlet measurement or detailed installation dimensions are supplied.

Skip it if you need a defined inlet size for fitment; the KJTYSDM 51 mm Ninja 650 slip-on specifies one, but is not a full system.

This suits riders seeking a full-system change for one of the named Kawasaki models and interested in the stated airflow and sound aims. Keep its 2012–2022 application in view; inlet and installation dimensions are not given.

7. QWRXDGS 650 Full System

Best for: Sparse-listing full-system shoppers.

Why it ranks #7: The title names Ninja and several 650 models, but the supplied details give no fitment years, inlet size, or construction information.

A full-system muffler is the clearest specific detail in this QWRXDGS listing, which names Kawasaki ER6N, ER6F, Z650, and Ninja 650 applications for 2012–2022. The listing provides little supporting construction or installation information, so its appeal is chiefly to buyers investigating that stated application.

The title describes a full-system muffler and identifies several Kawasaki models, including Ninja 650, with a 2012–2022 range. That gives a starting point for narrowing the application, but the supplied specifications identify the compatible vehicle type as ATV, creating uncertainty for a motorcycle buyer. No material, inlet size, connector design, or installation steps are supplied here, so the listing does not provide enough detail to assess those practical aspects of an exhaust change.

Skip it if you need confirmed motorcycle compatibility and installation dimensions; this listing identifies ATV as its compatible vehicle type and gives no inlet measurement.

Consider this only if you are evaluating the stated full-system application and can resolve the ATV specification against your motorcycle. The sparse listing supplies no material, inlet, or installation details for a confident fit assessment.

#8

8. Generic Universal Slip-On

Best for: Daily-riding flange-fit buyers.

Why it ranks #8: Although its title mentions Ninja 650, the specifications identify the compatible vehicle type as a car and provide no Ninja-specific fitment range.

A flange intended to match the original header pipe is the practical focus of this universal-style muffler listing. It also describes a moderate exhaust volume for commuting and mountain-road riding, while reinforced hanging points and frame-bracket installation inform buyers considering a replacement tailpipe.

The stated installation process aligns the flange holes with the original front exhaust pipe, then calls for evenly fastening the bolts and hanging the brackets on frame suspension points. That offers a defined mounting workflow for a buyer whose existing header and bracket locations match. The listing also says the outlet directs exhaust gas to avoid backflow and describes its volume as moderate for daily commuting and mountain roads, making those stated uses more relevant than a performance claim.

Skip it if you need a named Ninja 650 model-year fitment or inlet diameter; this listing provides neither specification.

This may suit a rider prioritizing a flange-mounted tailpipe and the listed moderate-volume use for commuting or mountain roads. Check the original header holes and frame suspension points, since specific Ninja 650 year coverage is not stated.
