Allright so my stock exhaust cracked at the muffler on my 2012 Rzr 4 800 and I threw on a Big Gun slip on eco. It sounds great but should I buy a programmer for just a slip on. As far as I know you dont need a programmer for "just" the exhuast only if you do more mods like bore, turbo, supercharge, alter max RPM’s….Let me know what you think!!! Thanks!
