I have done that exact thing on my M3. I bought a second OEM mid pipe with the secondary cats cut out and replaced with straight pipe. Very happy with the results as I have added aggressiveness and better tone, but not being overly boy-racerish like all the exhausts out there.
The Check Engine Light will only come on if you mess with the primary cats.
