White Smoke And Hot Right Exhaust Pipe???

[iLikeMustangs809]

Hey guys so I noticed that on my 07 gt the right exhuast pipe will spit white smoke on start up and will be very hot after driving, while the left side doesn't smoke at all and is relatively cold after driving. The right pipe also looks 2x dirtier then the left. What could be causing only 1 pipe to do that? I have no cats and a H pipe, also cams.

Sounds like you may have a blockage on the left side 'cause the right side seems to behave normally.
You might want to get the car up to temperature, put it up on a lift, and see how far forwards the left side of the exhaust feels relatively cold (an infrared thermometer would help there).

Is it running OK? Smooth? Perhaps cam timing on one side is too advanced/retarded somehow? Did this start after a mod? If so, double check the work. If not, maybe a sensor/solenoid causing problems. In addition to what Bullitt95 says, start with what he said.
