ok i am finally sick of filling my car up every other day to write this thread. about 5 minutes after i finished my exhaust install, O/R X and violator catback and mil elims from LMR. granted i drive it "spirited" but i did before i got the exhaust on and my gas mileage was no where near as shitty as it is now, im talking like 9-11mpg right now, AND my CEL is on!! i KNOW its the mil elims. anyone ever heard of mil elims not working? what can i do about it? and finally is it normal for mpg to drop greatly?
