Whitelightning Posted July 25, 2005 Share Posted July 25, 2005 Ok people listen in !! Just a question about the fumes from my exhaust. I started her up and decided to observe the change in fumes from the exhaust over time. (I don't get out much !!) For me the following happens (assuming I just sit at idle post start up): Minutes 0 - 2: Grey smoke Minutes 2 - 4: Lighter smoke Minutes 4+: Practically invisible smoke (even on revving Bruuum bruuum !) So in an attempt to catch out the exhaust fume geeks I thought I would open the discussion on whether this was ok, what other people see with their exhausts and what we should be looking for in a healthy (abeit modified ) Supra. Take it away boffins !!! Quote Link to comment Share on other sites More sharing options...
Class One Posted July 25, 2005 Share Posted July 25, 2005 Not being a techie at all, yours does what mine(unmodded) does. Start up white/steamy smoke after a few mins diminishes to nowt and nothing on opening up the throttle. (Edit BTW I'm not a geek by any stretch of the imagination!)

carl0s Posted July 25, 2005 Share Posted July 25, 2005 when the weather was cold, before the summer, mine smoked like a muvvahugger as soon as I had both my CATs removed. It was white smoke and it stopped once the car had warmed up. For some odd reason, this doesn't seem to happen anymore since I changed my exhaust to the RS*R. Perhaps it's just the weather.

Whitelightning Posted July 26, 2005 Author Share Posted July 26, 2005 Maybe it was deposits in the exhaust being heated up, smoking and then being blown out. Quote Link to comment Share on other sites More sharing options...
