secondary decat questionHi Guys.
I've been looking at what can be done to gain a bit of noise and maybe some power from the standard exhaust system without spending £££ on a Milltek.
There are 2 sets of cats, the main cats right at the front of the car and then a second set slightly further back.
My thoughts are to remove the second set which will hopefully make the system a bit more free flowing.
My worry is if this mod brings up any fault lights on the dash?
I originally thought it would but looking underneath the car the lambda's are in front of the cats so surely changing anything after the lambdas wont affect any gas readings therefore wont show any faults.
Has anyone done this mod to their car, and what were the results?
