Im thinking to buy this one but not sure if u need a jetting kit or other work before putting it on. I have a 2009 ttr230.

A: Yes generally when installing a complete exhaust system you will need to re-jet. It would really depend on your location (altitude/temperature) and how your bike is running with the current jetting. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike. I would recommend taking your bike to a local motorcycle dealership’s service department to have your bike properly jetted.

Q: DRD EXHAUST TIP?
2 years 5 months ago
Is the black tip a replaceable part a DRD exhaust as mine has a big gravel rash on it. If so I was chasing a ball park price. My bike is a WR450F 2008. Thanks in advance. Tony

A: Unfortunately we do not carry a Dr D end cap for your WR450F. I would contact Dr D direct and see if they have one.
