Need to remap?

Hi Guys, I recently bought a 2010 Busa with Racefit slip-ons as shown. The inside of the slip-ons are brown & dry without a trace of carbon soot (My Gen-1 used to have black, carbon soot). Is it normal for Gen-2's to have brown colored insides on the exhausts (due to the presence of the O2 sensor which governs the mixture), unlike Gen-1's , or is my bike running lean due to the shorty Racefits? (bike has not been remapped after installing the slip-on's). Looking forward to opinions from the helpful whizzes here :) Any info appreciated:bowdown:

Idk? I've always been told and read that you shouldn't have 2 remap for just a slip on pipe. If it was me I would add a PC or a Bazzaz and take it somewhere and get it dyno'd just so I know 4 sure that it's tuned and running perfect
 
no need for slip on. will it run a bit smoother map yes but for slip on I would spend the money else where like suspension
