They used to be, but I believe Van's has a new supplier.

Ditto on the trombone exhaust. Perfect if running the cold air sump. I am not yet, but plan to do so.

EDIT: Almost perfect. I had to put a small bubble in my James cowl to clear the left side tail pipe clamp.

Default Sky Dynamics

I have a Sky Dynamics, 4-into-1 exhaust with the downturned tip. This is on a RV-8 with a parallel valve IO-360-A1A with 10:1 high compression pistons and LASAR electronic ignition system. 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.

When I replace my engine, I'll probably go with Sky Dynamics again, given my good experience with their exhaust.

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.
