my car smoked a little before hand (my turbo seals are going out)...and today i put on a test pipe, and dumped off my exaust just as it turns behind the seats, and now it smokes it's *** off...any ideas?

 

your cat was probably absorbing some of the oil and it was cooking off inside with a little smoke, but now you have a unrestricted pollution dispenser setup....

get teh oil seal changed out on it before it flows oil....
