RE Pros & Cons of different exhaust systems (4 to 1 vs 4-2)
…DanH
As originally delivered around 2008, the Aerospace Welding 4 into 1 did indeed hang too low:
I made some measurements, and sent it back for a straightforward mod; lop off four cylinder flanges, shorten the headpipes, weld on new flanges. That raised the whole assembly and inch or two. I do not remember the exact dimension.
I've been very happy with the pipe. It's now at about 1300 hours.
The 4 into 1 may or may not make more power than other choices. Longtime readers know I'm more interested in drag reduction as a better path to good cruise speed. The key advantage in that regard is a single tailpipe is easier to work with in terms of exit velocity and good outer surface shape. This was the ultimate goal:

Although I have an RV-8, I don't necessarily think this question is specific to that model, although the reason for asking may be specific to my installation. I have a 4 into 1 exhaust system (not Vetterman - not exactly sure of the manufacturer, but possibly Aerospace Welding who are now owned...

Impressed by the quality of some aluminium products out there, but not liking the cost (espcially with foreign conversion / postage issues / tariffs etc!), i decided to design and 3D print some of my own. Thought i would share here in case anyone else wants them. They can be downloaded here...
