I have searched all over trying to answer this question and have had no luck finding an answer.
I currently have (for almost a year) the Magnaflow catback system #15671 with the 4x9x14 SS high flow mufflers. I want to just replace the mufflers with Magnapacks and need to know if they will just bolt into the existing system, or if they will have to be welded in??
Thanks in advance.
