I just installed a O/R X pipe about 2 weeks ago, and now it smells like there is unburnt gas coming out of the exhaust, is this ok? Could the x pipe cause the car to run lean or rich? and if this is a problem, what can I do to fix it.
Thank You
I got 165 miles out of the first half and only 90 miles out of the second half :shrug:, this was with about 70% highway driving, about 21.5 mpg.
The best I ever got was 26 mpg on my way to florida, all highway.
