Default smoke from one tailpipe

my dad was following me and said i have smoke or steam or whatever that v\comes outta one tail pipe. i have also noticed when i first turn it on when its cold that they both have it but the right one more than the left. Its not smoke but like a steam or something. I have an off road X and SLP Catback. My dad says it could f*ck with the cylinders or something. I thought it was normal I mean i havehad this set up for a while and have not notice any problems. what ya think? thanks.

I think its normal when you have a o/r midpipe. I have a fair amount of smoke come outta mine too. Since i've had the o/r pipe, i've realized it, before I don't recall anything. Check out my vid Teh Stingers

You can see the smoke comin out of my tailpipes, is that what you are describing?

Do you have an "H" or "X" pipe? If not, then you may have a leaking head gasket on that one side. Check your water level in your radiator often to see if you are losing anti-freeze. If so, you need to replace the head gasket.

according to his post he has an off road X.

And yes the stangs come with a stock H.

I'm assuming its b/c he has an off road pipe, mines o/r and I seem to see the same thing he is describing, tho i'm waiting for him to confirm from my vid...

It could just be condensation in your exhaust pipes; normal.

Check your oil ASAP! Any milkyness means you've got a blown head gasket. You can get a "block test" done cheap. That will detect exhaust in your coolant. You can also pressure check the cootant system cheap. Last resort: "leakdown test". Costs more, but will give you the truest indication of how tight each cylinder really is.

You may want to pull your throttle body and check for oil on the floor of the plenum. Turbos and blowers often require a breather assembly to prevent oil from being sucked out of your valve covers... mine did that.

It's probably condensation.

Let her idle and take a whiff, you'll easily be able to tell if you are burning anti-freeze or anything....

hmm did you right click, save as? Should work. But anyways all it is me revvin in neutral, you can see smoke comin out of the tailpipes, at one point there is quite a bit. Just thought I would give you something to compare your situation to.
