you don't need to remap your FI if you just get a slip on.

if you get full system... then you'll need something like a power commander.

What sort of bike?

You may need to either remap your current ecm, or install a different ecm if the bike is fuel injected (depending on the pipe you get)... or re-jet if carbureted. What type of bike/exhaust are you talking about?

he's planning to get a gixxer1K K6.

and i guess he wants the two brothers pipe.

oh and to save time for the mandatory question... it's gonna be his 4th bike.

So, is this your first bike?

fifth street bike,, First liter
