So I had my car up on some jacks today because i was painting my wheels and I've been planning on getting a 2.5" bolt on catted ZZP DP and I was looking at the exhaust under the car and I could only see where it bolts on in the front of the car ... where does the DP bolt in the back? at the Y? because I saw no bolts to take out there. Anyone put one of these on before and have any help? thanks
