Hi all, i need some help/advice. I had a replacement section made for my exhaust (middle section just behind cats), to remove the middle boxes. Since i had this done on friday i have noticed white smoke from the car. It only does this when the car has been left for a while (overnight). When i start the car, it doesn't blow plumes of smoke out, just a little bit of condensation smoke. but as soon as i pull off theres a nice white cloud of smoke then nothing, it seems to clear itself after pulling off. I noticed today when i finished work that it only smokes from one side (passenger side). Its kinda looks like condensation smoke as it's not very thick, doesnt really smell, and isn't blue or black. As soon as the throttle has been "blipped" a couple of times... hey presto... no more smoke. This has literally only just started since i had the middle boxes removed from my exhaust system. I left the cats in because of the horror stories about the turbo seals going etc so thought this would of been okay. Another thing to note, i have noticed recently that the car seems to "surge" a little and every now and again, will miss slightly. Also have a smell of petrol when i first start the car but dissapears as soon as the car is warm. I don't know if it's just me, but the car also seems to be holding back slightly on boost even though it hits and holds steady at 9psi. Just to mention the car is standard apart from an apexi air filter, stainless exhaust (cat-back) and an apexi afc thingy which i have no idea how to work so i've never touched it. Got my car booked in on tuesday next week for a rolling road set up and dyno so i'll ask them if they have any ideas as to the symptoms, but would just like to know if any of you guys have had these problems and what solved it?

anyone?

anyone?

 

Could be where the new section you put on is new, may take a while to burn off.
