I think the person who installed the headers and midpipe said the midpipe did not plug and play to his rear exhaust and that cutting and welding was needed. Maybe if Becker sells a complete kit with rear exhaust it will all fit. Don’t know. No one has reported on that yet.

Also, the +15 rwhp was over test pipes in a stock midpipe. It is possible the gains over an aftermarket fully catless midpipe might be only 5 rwhp. We don’t know.
