Raceline performance Spec Exhaust Flange – Engineered for Performance
The Raceline Performance Spec Exhaust Flange is precision-engineered to complete the exhaust port exactly how KTM’s own engineers would envision it — without the limitations of mass production.
From the factory, KTM uses standardized components across their range to keep retail prices in check. While the stock exhaust flange gets the job done, it’s built for cost-efficiency, not peak performance. That’s where we come in.
Our flange is a simple yet highly effective upgrade that unlocks untapped performance. Riders say it transforms the bike's power delivery — especially in corners — making it more third-gear friendly, smoother to ride, and improving rear-wheel connection.
If you're chasing better rideability without compromising reliability, this is the bolt-on mod that makes a real difference.
