I have a Magnaflow catback that drones like crazy at 2-2.5K rpm.
The built in resonator is 4in diameter and it's 14" long. The v6 version has an 18" long resonator. Would moving to a LONGER resonator help quiet it down or would a LARGER resonator do a better job. Or should I just fit the biggest effing one I can on there? And should I replace the current one or add a 2nd in-line.
