Our Two Cents

When replacing the OEM/stock exhaust with a full system exhaust, fuel injection remapping is required.Two Brothers recommends their Juice Box Pro or the Dynojet Power Commander.

This is also a great time to upgrade to a high performance air filter like K&N or BMC.

Fuel injection remapping systems and high performance air filters are not available for all motorcycle makes/models.
