do the flowpath mufflers that come with the mac cat-back system drone like flows ? i thought that they were chambered like the flows but do they have the annoying flowmaster drone ?
Just about every muffler is going to have some sort of drone @ around 2K (depending on what headers/mid-pipe you have also). The FLows are notorious in most applications to have a bad drone, but MAC's are better from what I've heard. They might have a drone, but not like Flows
