I contacted Clint at Vettermans. Good guy and easy to work with. I have the IO360M1B also on my 7 and his suggestion was the 4 pipe. I also have his intake tubes i.l.o. Lycomings. I should be receiving my exhaust in a few weeks from him.
Aren't they one and the same? I thought the exhaust that Van's sells were manufactured by Vetterman. That was the deal when I ordered mine for the RV-7 w/ -M1B anyway. Perhaps the RV-8 is different.
I have Vans exhaust pipes on my RV-8. Form, fit and finish are very good, but I had to add down turn tips to keep the exhaust from impinging on the exit ramp.

I have a Sky Dynamics, 4-into-1 exhaust with the downturned tip.... The exhaust system has over 2,000 hours and it has been very robust. I did have to have the 4-into-1 collector fixed once.
I'd recommend a 4 into 1, either Sky Dynamics or AWI, just because the tailpipe is arranged for a clean cooling exit...and there is no crossover to heat the fuel controller.
Read what Dave Anders has to say in the October issue of Kitplanes.
Van's not very new supplier is Van's. Been making systems in house for quite a few years now.
The systems for the RV-12, 14 and the common crossover system that will work on vertical induction 320's and 360's are produced in house.
I think I am correct in saying that anything else (540, angle valve 4 into 2, etc) that Van's sells is still produced by Vetterman.
