do i hav to takes them off on leave them on
 
could i not just leave them on if no y thanks again for the help foxspeed

the "slash cut" tips stop the diffuser fitting due to the funnels - i did just try fitting it but it wouldnt go on.

only two choices - remove tips so you can leave the funnels on

leave tips on and remove funnels and fit the tailpipe trims so the exhaust gas doesnt melt the diffuser
