Its not that bad of a smoke guys. Its not clouds to where people behind me wouldnt be able to see. Its just noticeable amount of puff when revved. If no revving and sitting on idle, its just noticeable out of the exhaust like when you start a car cold in the morning. The only difference is that I start it in the afternoon and its super hot outside and you can still see it. I do have some exhaust leaks and it has that exhaust fume smell. I haven't gotten a chance to go under the car yet. I'm hoping the exhaust is just old and cats are probably bad. The car runs super healthy and strong tho so thats good. ECU is code 55 and car has no problem driving or boosting.
