[LEFZ07]

hey guys new to the forum. I was just curious do I need any type of fuel management system for the bike if I get the M4 slip on?

I have this exhaust on my bike and it runs perfectly with no changes to the EFI mapping. Sounds GREAT too!

good advice dmrphy03 !
LEFZ07 - Did you get the slip-on. Was it round or could you get an M4-GT if you wanted. I have heard the M4-GT on a Suzuki 650 Twin; Gladius, and liked it.

How do u compare the M4 to Yoshi R77?
