2007 Can Am Outlander 800 Slip On Exhaust

I have been researching exhaust slip on’s for the past couple of weeks. I first had it narrowed down to Muzzy and LTE however I could not locate any Muzzy slip on’s for sale and LTE’s website looks outdated and not working correctly. I would like to go with LTE just not comfortable with service when the website isn’t working correctly. Guess HMF it is, I have tried searching but have not had much luck. What is the difference between the Performance HMF slip on vs the Swamp/Titan HMF series slip on?

Has anybody had both and liked one or the other?

Should I try to find a LTE slip on?

Also, adding a slip on how hard are the tuners to figure out? I am not tuner or computer wiz.

Thanks, TB
