Are you sure? SS V1 Stepped headers do not mate up to the stock section 1 with cats (unless you do some custom cutting/welding).
If you have SS V1, I would suspect you have SS section 1 with either straight pipes or race cats already.
I have SS V1 on my M Coupe (and installed them myself) so I'm familiar.
