HEy guys, I am new on this forum! Glad to find a local forum that isn't 100+km away~~

I have a question tho, few month ago, I had my cats removed to "simulate" those track pipes sold over 700USD! However, a tech at Dinan told me that I will run rich and actually wash my cylinders w gas! NOT good...+ i am gettin horrible mileage! what do u guys think i should do?? :confused:
