I think my dual carb 300T sounds OK W/the stock flex pipes. $150 for 2 Turboheaders is a bit salty for my taste. Note the extra support bracket at the ends as well as the standard OEM bracket.

You can see the auxiliary bracket at the ends of the pipes at 2:30 & again at 5:50. The bottom of the test stand is a duplicate of the motor mount box on my 1/3 scale SIG Spacewalker. The flex pipes make for a very tidy installation W/the exhaust exiting in a scale like manner. Given the airframe that it is going to be installed into, it has ample power.
Here are some PIX of the auxiliary bracket. It is made from fuel line clamps W/K&S brass bar stock.Also note then crankcase breather exit next to the exhaust pipe. The velocity of the escaping gasses scavenges the oil into the exhaust stream.

The 1/3 scale Spacewalker should come in around 20#-22# so vertical performance should still be impressive W/the FA-300TTDP twin. I am forgoing the dummy engine as the heads & about 1/2 of the carburetors/velocity stacks will be protruding from the cowl on each side. Why have a dummy engine when you can have real engine components showing?
