Outlander 800 aftermarket exhaust

[Starbuc71]

Has anyone here installed an aftermarket exhaust on their outlander 800?  If so, which brand seems the best and also is there any modification with the fuel injection.  Someone told me you have to purchse a programmer if you change the exhaust.  Let me know.

I just 30 minutes ago stuck an HMF exhaust on my 800 max. Gotta eat, be back soon.....she can't wait.....   I need help with my dobeck HMF Optimizer, does it matter which plug goes on what cylinder??? There aren't directions, the wires are color coded but do not match any wires on the 800.
