Consider that the 99 and 00 M Coupe doesn't have a spare, due to the space taken by the current exhaust system, or so it is said. A larger engine would just compound the problem.

Even a slightly larger exhaust spec on the M3 could make a significant difference in back pressure. 2 times the diameter is 4 times the area.



I'm fairly certain that the exhaust on the M Coupe's has been said to flow BETTER than the E36/M3, so I agree, that it is hard to believe that the exhaust accounts for 15 less horsepower than the E46/M3.
