Tip, completely loose rear header when pulling the oem silencer off the bike no need to loosen front headers at all. If installing SC project I recommend loading XECU mapping which is maps created by SC project development department, so mapping is specific for the pipe and bike but is not limited to brand of motorcycle or brand of exhaust, they have specific mapping for all. Is XECU mapping is loaded no need for servo dummy plug, the XECU map has the servo function disabled. Mapping is required when fitting any new exhaust to a bike and fueling has to be adjusted if you want to achieve the correct performance expectations.
