My 2003 Mustang GT before and after the exhaust mods that i have. first is stock, then after the weld in flows, then after the cats were cut out. Last ones the best.
might have made a mistake..not sure if the first one has flows or not....
Do you have the check engine light after the cats came out? I did the same thing to mine but I can't get rid of the check engine light and also I noticed a slight increase in gasoline consumption
yeah i had the check engine light on. but i bought a diablosport predator handheld tuner, which i was able to turn it off with. yeah i get about 15 mpg. but i also have 3.73s too, and an auto
