I don't think you can. At least not legit from BMW.

You can fit an M Performance exhaust though. Power difference is minimal and all top end if you look at dyno graphs.

There is ZERO power difference with MPE, don?t fool yourself.

The ZCP Exhaust will sound slightly better.

You?ll need an aftermarket tune for the rest you?re looking for.

I meant stock M3 vs ZCP M3. Not MPE.

A must buy for M3 or M4 cars

Had a very good deal from Rob at AA
