do you have any idea how many dollars and man hours honda spent during R&D of that bike to get the tune just right??? Neither do I but it sure was a lot damn longer than it took you to undo it.

There are no twin cylinder XRs. You're probably looking at the exhaust, it just has two exhaust ports. All XRs are single cylinder

don't you have to rejet the bike?? it will run lean if you don't. translation: your header will get hotter and so will the engine and might cause valve problems.
