Has Fresh Air Exhaust (FAE) changed your wake?

I have to admit that it looked a lot cleaner before when you could only see the stripes of the hose clamps against the black tubing and you didn't really see the aluminum angle "attached" to the tubing. But this way it's even more bombproof than before.

I think I could have easily gotten away with just the Stainless steel extension on the plastic exhaust output flange, but I figured I might as well over-build it since it failed twice before...




Alternatively, I could have used some kind of U-bolt setup instead of the hose clamps, but I'd already bought those and they seemed to be holding quite well. Really you won't even see the hose clamps attaching the tubing to the aluminum angle bar unless you get up under the platform and look...

Oh damn that should do it! If it comes off now, physics were some how broken.

Here is the wake at 30mph for skiing. (on rougher water)


And with the surf wave, you have no idea it has anything other than the quieter and the lack of fumes.
This is with my wife driving and my son on the non-surf side.

Looks great man. I am redoing mine when i pull my boat out. I now know what i need to do. Mine is also acting like a trim tab and messing up my wakeboarding wake. Did you oval the down pipe at all?

It's probably something I'll do in the off season. For now, it's working. I did end up having to cut an inch off the bottom of mine because of the drag actually putting enough leverage to pop the rubber couplers off the exhaust flanges. The real FAE actually ovals down to less than 2" wide!! that's a HUGE difference from my 3.5" ABS. I know if I used PVC I could heat and oval it, but I tried to heat up my ABS and oval it using my bench vice and a heat gun and it didn't seem to do anything. I will likely get some aluminum for the downpipe and make it more oval. But for now it's working. The extension on the exhaust flange was the ticket for me.

Trayson, you are the king of DIY. That is amazing!

I am going to use a 4to 3 inch 90 out of the stock exhaust. The 4 inch slip perfectly into the stock lip and then i just rivet it dirctly to it. It all makes sense in my head. I will post it when i get it on in a couple months.

are you talking about simply having a downturn of the stock exhaust outlets so that you'd have two pipes just sticking down in the water? or are you intending on doing what the FAE does and join them together so that the downpipe is in the prop wash?

Doing the the same as you. But not using any rubber at the boat. This is what i had. It worked great but was draging in the water when up to speed. So i found some adapters that will algle it up much like yours.

FYI, the TEE that you used was way too wide for what I was trying to make work on mine. But getting the one with the screw fitting on the center of the tee was great. kept it compact and made it so everything fit. I think it's called a cleanout tee. so if you come up constrained on width, keep that in mind.

Look forward to seeing what you come up with,
