I have an 05 S that the muffler is rusting out(drivers side). Trying to figure out what to do without replacing the whole system. Any thoughts?? The whole system is $700-$1000,way to much! Thanks for any ideas. Scot

This is the mod I was looking for. Not only is the original “dual” exhaust design stoopid, it’s very expensive to replace. In my case, the “odd ball” happened to rot out (new england weather) which is common. Since most of the airflow naturally exits the ball to remain, the other one does not get as hot and has a tendency to rot from the inside out and fail. All the other components are in great condition. You just saved me a bundle as I’m looking to sell my mini, thanks for posting this!

I guess i’m no going to ask a question here since none of the other questions were answered.

O2 sensors are before and after the cat and are not associated with mufflers or resonators. Should not affect electronics or 02 sensor. I would like to see a Y-pipe used and the resonater replaced for a dual out setup with smaller dual mufflers.

It would be awesome to have some sort of remote activated butterfly valves and some actuators. that way i could choose one ball or 2 whilst on the go. cant be too difficult…

No side effects at all. It has been excellent and the volume is just right.

I rev the engine more I think

Any side effects to this mod? I mean, fuel consumption wise or any others?
