Recently I noticed that my Apexi exhaust seems to spit a little water when I rev it high. Damn it loud when some one get on it (and my head is near the exhaust) Any cause or damage that can be caused by it spitting a water mist out?

 

Water mist is usually bad gas or condensation -- bad gas you would be able to tell from bad performance (likely), but condensation is just visible only when the car has been stopped while it's cool and humid outside.

Water can rust exhaust pipes, and while the outside of your muffler may be stainless steel, it's likely the insides are standard steel or iron. Both rust, and both would break down if in contact with water for long periods of time.

backwards..hehe. I only use the higheest grade gas EVERY time. So it shoulnt be bad gas. It was kinda coolish out (night time)when this was noticed. So im assuming this is normal. Just me worring. Oh and Fred..that damn sub blew! ( X=plode for me now..hehe

 

Highest grade doesn't always mean highest quality. Gas "breaks down" with time into lower-octane levels. The high-grade, high-price gas is the slowest selling gas the station has on stock, so it tends to sit in the storage tanks longer; this gives it more time to sit there and "break down."

It sucks, I know. I try to split the difference and go with mid-grade. I've tried all three, and that seems to get me the best performance for the money.

A cool tangent...I've noticed some stations now have pumps that will mix the gases for you! They have the usual three octanes, and then two extra buttons that offer you mixtures of the three fuels for more octane options. Prettydamncool, in theory at least.

 

U blew it up??? damn, u should get something better then a xplode if ur goin to push it that hard

 

Water is a normal byproduct of the combustion process, regardless of fuel quality. (You can see the water vapor in car exhaust on cold winter mornings.)

It sounds to me like you may have some of this water vapor condensing in the exhaust system. This is normal, and not anything to worry about, unless it's pooling up at a low spot. That can promote rust, as another poster pointed out.

It should dry out after the engine's been off for a while. If you get lots of water out of the tailpipe after the car sits overnight, that would indicate that it is not drying out. In that case, I'd probably consider contacting the manufacturer of your exhaust system and asking them about it.

Hope that helps. smile.gif
