    Any shot a set of well designed aftermarket headers would make sense on a s65 m3?

    Thanks for the kind words guys, they are appreciated!

    S85s/S65s have the best factory exhausts I've ever seen from exhaust port to tailpipe.

    I've posted this before but a proper cat delete with nothing else changed to the exhaust will outrun an identically equipped M3/M5/M6 with full catless or catted Supersprint exhaust. I say proper because you can't just gut the primary cats and expect the same results.

    The difference between the supersprint and modified stock exhaust cars (both running the same software/filters) is about 10 cars at 200mph, no joke. To the extent that both owners agreed to swap exhausts and run again, same result, modified stock exhaust > by 10 lengths launch control used in both cars off the line, same shift rpm, etc. You can guess what region of the world this was in.

    Anyway, you can have the best exhaust in the world for your car (performance wise, sounds great as well as there is no drone and no volume increase until ~5000rpm) for a few hundred bucks. Props to BMW.

    I cut my primary cats out. Never ran quicker with a full exhaust at the track...
