no mate they just clamp on at the ends,i've read your first post wrong,sorry,thought you where going from 197 to 200 but as your going the other way the exhaust will be fine,the tips will just stick out slightly and not be slash cut like normal 197's,as said though the tips just unclamp and knock off so you can change them if you wish,ktec will sell you the 197 ones iirc
