So I've been looking at the full system Arrow street thunder exhaust for the XSR700 (the exhaust is officially for the MT07 but fits the XSR). The exhaust is a high mount straight through system.
I've heard the XSR700 and MT07 run pretty lean from the factory and adding a straight through exhaust only makes this condition worse. However it seems to be a 50/50 argument as to whether it's an issue or not, as a lot of people say the bike self adjusts to the new fuel ratios, while others say the bike barely adjusts and still needs remapping.
So my question is, should I get the ECU flashed and remapped when I add this exhaust or should I leave it be? The only reason I'd get the ECU flashed is for the machine's health with the new exhaust, performance doesn't bother me at this point in time.
