The Kawasaki Ninja 650 is one of the most popular middleweight motorcycles in the market. Combining a sporty design, responsive handling, and rider-friendly ergonomics, it appeals to beginners and seasoned riders alike. But for those looking to unlock its true potential, performance modifications can make a world of difference. One of the most impactful and accessible upgrades is an aftermarket exhaust system. This guide will walk you through everything you need to know about upgrading to a Ninja 650 Delkevic exhaust, including its benefits, installation, and what you can expect in terms of performance gains.
Why Modify Your Ninja 650?
While the Ninja 650 is already a well-rounded motorcycle, it does come with certain limitations. Manufacturers have to meet noise, emissions, and cost standards, which often results in stock parts that restrict performance. An aftermarket exhaust system is one of the easiest ways to improve engine breathing, reduce weight, and enhance the auditory experience of your ride.
Benefits of Performance Mods
-
Increased Horsepower and Torque
Aftermarket exhausts reduce back pressure, allowing the engine to breathe more freely, which often leads to modest but noticeable power gains. -
Improved Throttle Response
With better airflow, the engine can respond more quickly to throttle inputs, giving a sportier, more connected feel. -
Weight Reduction
Stock exhausts are typically heavy and bulky. Swapping it for a Ninja 650 Delkevic exhaust can reduce the bike’s overall weight, enhancing agility and handling. -
Enhanced Sound
The stock exhaust on the Ninja 650 is relatively quiet and tame. A Delkevic exhaust offers a throatier, more aggressive tone that many riders find more satisfying.

Types of Delkevic Exhausts for Ninja 650
Delkevic offers several options for the Ninja 650, each catering to different rider preferences in terms of sound, style, and performance.
1. Mini 8” Stainless Steel Round Muffler
This is one of Delkevic’s most popular models. It delivers a sharp, aggressive tone without being obnoxious. Perfect for riders who want a noticeable sound upgrade without going overboard.
2. Carbon Fiber Oval Muffler
Lightweight and sleek, the carbon fiber model offers both visual and performance upgrades. It reduces weight significantly and gives the bike a more race-inspired aesthetic.
3. Stubby Muffler Options
Stubby exhausts are shorter and more compact, giving the bike a muscular and modern look. These typically produce a louder and deeper tone, ideal for riders who want their Ninja 650 to sound as aggressive as it looks.
Performance Gains with a Ninja 650 Delkevic Exhaust
Horsepower and Torque
While the Ninja 650 isn't a high-horsepower machine to begin with, a Delkevic exhaust can improve its output by 3-5%, especially when paired with other modifications like a high-flow air filter or ECU remap. The difference may seem small on paper, but it translates to a crisper, more responsive feel on the road.
Throttle Response
Most riders report a noticeable improvement in throttle response immediately after installation. The engine revs more freely and power delivery feels smoother, particularly in the midrange, where the Ninja 650 does most of its work.
Sound Quality
This is often the most immediate and noticeable difference. Depending on the model you choose, the Ninja 650 Delkevic exhaust can offer anything from a refined growl to a loud, race-inspired roar. Most systems include a removable baffle, allowing you to tune the sound to your liking.
Installation Process
One of the reasons Delkevic is so popular among DIY riders is the ease of installation.
Tools You’ll Need:
-
Socket wrench set
-
Torque wrench
-
Screwdrivers
-
Anti-seize compound
Steps:
-
Remove the stock exhaust: Start by unbolting the OEM exhaust from the header pipe and rear mount.
-
Prep the Delkevic system: Make sure all parts are clean and dry. Apply anti-seize compound to any bolts or clamps.
-
Install the new exhaust: Bolt the new exhaust into place using the provided hardware. Align the system properly before tightening.
-
Check for leaks and alignment: Start the bike and let it idle. Look for any exhaust leaks and ensure proper clearance from fairings and foot pegs.
-
Re-torque after a ride: After your first ride, recheck all bolts to ensure everything is still tight.
Additional Tips for Best Results
Pair with a Fuel Controller or ECU Remap
Although the Ninja 650 can run a Delkevic exhaust without any tuning, for maximum performance and optimal air-fuel ratio, consider a Power Commander or ECU flash. This ensures you’re not running too lean, which can cause long-term engine damage.
Upgrade the Air Filter
A high-flow air filter complements the freer-flowing exhaust, improving overall airflow and enhancing the bike’s breathing ability.
Regular Maintenance
After installing a new exhaust, check your bike’s performance regularly. Look out for unusual noises, backfiring, or changes in engine temperature.

Whether you’re chasing better throttle response, a deeper exhaust note, or a lighter, more responsive machine, Delkevic provides an affordable and high-quality solution. With easy installation and noticeable benefits right out of the box, it’s a mod that offers real value for riders of all skill levels.
