Different exhaust systems can have an ENORMOUS impact on your motorcycle's performance!

Not only will different exhaust systems produce different peak horsepower and torque numbers to some degree, but WHERE those peak numbers occur in the RPM range, AND what the curves look like around/ between those peaks, can be WILDLY different from one system to another!
These dramatic changes in power curves also necessitate equally dramatic changes in tuning for each system. Be sure to ALWAYS have your bike retuned if you're changing exhaust systems!
If you'd like our custom ECU mapping for your specific system flashed into your motorcycles ECU, just head over to 2WDW.com. If your motorcycle is NOT listed on our site, then it will need to be tuned in house on our dyno. For pricing and/or to setup an appointment, give us a call or send us an email at [e-mail].
