There is a bunch of testing going on with the XTZ 1000 right now. I would hang tight on doing exhaust and intake at this time. Very soon i will know if the Ron Woods modifications are working.
i have learned that the engine is the last thing on this ride that needs help.
The vendors are here on this site. We just don't have a specific vendor section at this time. That we participate in I should add. lol UTVcrap.com is a great place to start!!!!
But if you ask they will stop by and give you there info. Just not sure how many are working on exhaust and intake. Seems like most are working on safety first with this rocket ship.
And yes for a full exhaust and intake it looks like we will need a fuel controller.
