Will a buschur 3in DP work with a Apexi Dunk catback? It doesn't seem like it's going to reach the catback and at the start of the catback, there's a flange there. I know i will eventually have to cut off a part of the catback if it does reaches. Also, the catback pipe seems a little bigger than 3in. Anyone know if it will work or anyone running this setup. Any comments would be nice.
