My definition of catback would be where the midpipes end, that flange to the rear of the car. Now, there is that Y pipe that hooks to the stock mids(which i have on the car). I was unaware that was considered part of the bmw performance exhaust. I thought it was just from the last flange back.

Sorry about confusion.
