Tail Pipe Emissions Testing: While this cat section is
very efficient at cleaning tail pipe emissions, due to varying laws
from state to state, vehicle configurations and tune *Passing
emissions testing can-not be guaranteed on every M3*
Testing in California: This system can pass "sniff test"
on most M3s but has no CARB Exemption number.
Properly running stock and even modified M3s have passed
with this center section in the past. However, please consult your
appropriate state office or Smog station if you have questions on
the legality aftermarket catalytic converters. Due to recent
legislation changes in California, we sell these systems to CA
stating "for OFF-ROAD use only".
