"The SAS works together with the catalytic converter in the exhaust cans, also to reduce emissions. If you have aftermarket cans it is pointless and can cause problems. Removing the SAS is not recommended with standard cans"
My 950 SMR had this and the EPC mods done before I bought it
I had my KTM 990 Adventure remapped last week with these guys. I can highly recommend them.. It's changed the bike completely.. Allot smother and 10 extra BHP http://http://www.raceengineering.info
