There is an increase of noise, more like a lower/heavier noise....... Racier I guess!
Theoretical there is also an increase of power, but when there are two O2 sensors (before and after cat., it's the OBDII system) it could be the engine management (Bosch Motronic) should switch over to the emergency course. This means a more bad mileage and even a DECREASE of power. | Thanks for the info!
its a 93, so OBDI
one (?) O2 sensor infront of the cat.
