What exactly is "reversion?

What exactly is "reversion?
I have black rubber external flaps on my exhaust. I was thinking of switching to an angle cut tip exhaust tip. Everybody keeps saying watch for "reversion"
Please help.
Thanks

Re: What exactly is "reversion?
reversion is when water reverses and come back into the motor through the exaust usually when you come off plane. the rubber flaps help prevent this as do the flappers in the pipe,

Re: What exactly is "reversion?
Hmmm, well, reversion is really when the water in your exhaust system ( in a wet exhaust system) is sucked back into the cylinder through the exhaust valve during valve overlap at idle. Valve overlap is when the exhaust valve and intake valve are open at the same time. The flapper at the end of the exhaust pipe doesnt have anything to do with it. It does help stop surges of water from getting in your engine when it is off or if it quits while you are running and that big surge of water comes rushing forward.

Re: What exactly is "reversion?
formula is correct except that just water from the exhaust wont come back unless there is an abundance of it hence coming back in from the exhaust through hulls

Re: What exactly is "reversion?
Sorry, but Formula is RIGHT! Unless you are running a strictly dry stack exhaust, there is always water in the pipe and "outside abundance" has little or nothing to do with REVERSION. Now, to the point; If you are changing to an angled style exhaust tip, I suggest that you purchase ones that include the internal flapper. Your situation will be as good or better than it is now. --- Jer

Re: What exactly is "reversion?
You can purchase angle tips with internal flappers, then you have no worries. The flaps will protect you from the potential water surge that you get when coming off plane too quickly. But as formula said, reversion is from excessive cam overlap, and the water exiting your engine getting sucked back into the exhaust at the point where the water mixes with the exhaust gases. Thats why they sell long risers, and dry pipe systems.
