Most "new" exhaust need to burn out/clean out the exhaust system. Everything has to work up to temp for a couple of days.

Also after about 100 miles you are supposed to check the exhaust bolts and make sure they are tight.

yup that could be the problem becuse the o2 sensor is what monitors the fuel to air ratio after burnt

also what they are talking about on the new exhaust systems smoking is that they are usually cooled and coated in oil for long life and looonger shelf life
