4 Into 1 Exhaust

Cooool. I think Exhaust Technologies can make up a 4 into 1 for the "A" model. I think they may be working on an off the shelf version. You can mock up a system using some parts they send you with some PVC pipe and they will make a custom system.

Any way the guy who made these has a real eye and they look nice, please send the never version.

QUESTION on the PICTURES?
Could you tell me what the SUGER jar is with what looks like a scrub pad?
-and-
What the purpose of the metal strap is under the alternator pulley?

I used the Sky Dynamics 4 into 1 exhaust on the O-360 rv7

My only problem, which was considerable, is that the tube arrangement conflicted badly with the filtered airbox.

I didn't use vans donut filter and had to build a custom model with a panel filter.

That's only common to a carbed Lyc. Fuel injected may be totally different.

I really like the setup after I finally finished it. I think I just wanted something alittle different than the plain vanilla rv.

sound is fine. Its no louder than the crossover vetterman.

Looks like an "interesting" oil separator for the crankcase breather. Probably not the best location for a glass jar of that size...

I was initially thinking a heat shield, but after looking at the 1st and 3rd pics closer, I'm back to wondering about it, too.
