i have an 89 gt with a few slight mods. it has a cam, cold air intake, msd coil, 3 row radiator, and an electric fan. this past week I had my new exhaust put on. it consists of mac 1 5/8" long tubes, 3" catless h pipe, and 3" cat back. Before the exhaust was put on, the car ran perfect. after the exhaust, the car ran rich. I was able to smell fumes when I was idling and sometimes when I drive. one of my buddies recommended swapping the 02 sensors for heated 02 sensors. he said that the 02 sensors required a specific amount of heat from the engine that got reduced when the long tubes got put in. need some help. any recommendations?

really the car needs to be "tuned"..any dyno shops in your area? You might be able to get Brenspeed to work with you
