the downpipe might be 3" to 2.5" flange to bolt onto oe exhaust if you have the oe cat in place then you need a downpipe that has the 2.5" flange.Both previous classics ive owned had a H&S 3" openneck decat with 2.5 flange
Ask the seller what size is it at centre pipe.If its 3" all the way then you would need a 3" exhaust also.
