Ok, I am ready to get rid of the pre-cats. Unfortunatly, I will not be able to really tell if it's made a difference or not becaus the car will soon be garaged for the rest of the fall and winter seasons. New mod and I don't even get to take it to the track before it closes down. So for those of you who have headers or just gutted the pre-cats...What can I expect? Is there loss of power down low but a burst of power in the mid range? Any draw backs? Just asking before I go destroying them and connecting the MIL Eliminators. Appreciate any response. Thank you
