Have you ever heard of a butterfly valve in reference to the exhaust pipe being installed on a 1999 Saab 9-5 Turbo? I had pipe replaced and ever since, there is bellowing smoke coming from the exhaust pipe. Someone told me there was a "butterfly valve" located where the pipe connects and if not careful, the clip/valve could get flipped up and that would cause all the smoke. I haven't driven it for quite a while and can't afford to have it towed back to the muffler shop 25 miles away, plus it's been about 8 months since it's been driven. Was also told it could be the turbo gone bad. If it's the turbo, I will sell for what I can. Any help is very much appreciated!
have the same problem?
