E82 dual exhaust to quad exhaust??? Is it possible
Is it at all possible to take my twin exhaust and either make it into quad exhaust or a twin exhaust on both sides? I really like the look of 4 exhaust pipes in the back, should give me more power too correct?

No, not really more power. Maybe 10hp from removing the secondaries. It's all noise and weight reduction (less reduction if you add piping for the quad)

Yes it's possible but it will require a carefully made custom system. I had it spec'ed out a number of years ago. To be done correctly it was $$$$ and there were potential drawbacks from the quad system (loss of back pressure, increased turbo lag etc). All in all not worth it to me IMO. More of a cosmetic thing than functional. You'll find most quad systems do not actually have a fully open and functional 2nd "half" to them. Take a look at the undercarriage of the 1M....you'll see what I mean

Yes it is, here a picture of my previous car a 128i with custom dual exhaust. Axel back straight exhaust. And another picture of the design. Not the most functional, but was the less expensive route. Since this wasn't a performance orientated build.

The guy who was going to fabricate it was really concerned about the connection between mid pipes and axle back sections proximity to the diff. I was trying to do a system with minimal mandrels and the same size tubing from DP back. You could reduce the pipe size around the diff but performance use this makes no sense...IMO it's totally a cosmetic thing...
