MODs A or B for the GSX R750

I'm fine with either path, I'm just not sure which path provide more noticeable changes during rides

What MODS should I do for this Year, 2026. The remaining option will be set for mid / late 2027.

• Option A : -16 Front Sprocket + New Set of RoadSmart 4s Tires (190/55 Rear) (Cheaper, Less Expensive)

• Option B : Full Exhaust System with Dyno Tuned (MOST Expensive)
