So Since I just got a catless DP and I have a leak Im havin a h**l of a time fixing(my own fault I think rear flange) and no shops by me will touch my car without one soo I have 2 options. Have them make a 3" DP and throw the Magnaflow on there then sell my ZZP DP or have them chop up my ZZP DP and put the magnaflow in there. Cant call any shops today and Im just thinin of the most cost effective option. Opinions????
