Any one know how long something like this should take? I've had new exhausts before and those might smoke a little for 2 days or so, but this shit just keep going.
On the 350Z I worked on he had borla exhaust and I put on the twin test pipes and I had no smoke once I first put it on, I also got the CEL eliminators for them.
