The catalytic works perfect . But you have to do so extra work to make the sensor not to touch the second muffler , beside that works great and great price

This exhaust is really an excellent option for aftermarket exhaust.They are correct with absolutely NO drone. It sounds barely louder than stock and comes to life under throttle..It is extremely dificult to make the M3 sound great without spending a lot of $$... Corsa has done very well.I trackday this car and it performs well..Lets the car breathe easier and raises the top end some...Could be louder for track,but is excellent for street...In two words.....LOVE IT!
