Which Magnaflows did you have? The one with the mid mounted mufflers in the x pipe, or the one with the stock location mufflers?

When you had the Magnaflows did you have the X pipe or stock H pipe ? I currently have Magnaflow system 16732 with the stock H pipe. The only time I have a problem with drone is at 1500 rpm(70 mph) in 6th gear. I'm considering installing an X pipe.

I had the Magnaflows on my '02 with the x-pipe. It still droned between 1400-1600 RPM and it became even worse once I added headers. I tried all kinds of remedies to reduce the drone, but without any success. Supposedly measuring the frequency of the drone and building/installing a j-pipe (as mentioned above) will work, but I had given up fixing the problem and had sold the car (unrelated events) before I found out about the j-pipe. Went with the Corsa Sport for my '03 and there is no drone at any rpm.

Love my Borla exhaust and x-pipe.
I guess some people think the stingers drone. So they came out with the stinger II that actually has a larger muffler instead of the chamber in the pipe like the old stingers. I think the original stingers sound great.
Before the stingers and borla x-pipe, I had QTP electric cut outs on the factory h-pipe. Made the car sound like an old truck, and it droned like you wouldn't believe. Like at certain speeds, you could feel a resonance changing the air pressure inside the cabin. I don't get anything like that with the Borlas. I also considered Billy Boat Bullets, but was afraid it would be too loud. The stingers are a happy medium. At idle it's not loud at all. But really comes alive at around 3k rpm. But you can still have a conversation and hear the radio. It's not insanely loud, but is way louder than the stock mufflers.
