Tangerine EVO, - Six Header Update Options

First prototype of a critical component:

Looks like an MK exhaust muffler.

Looks like an MK exhaust muffler.

The only thing in common is the 6" diameter shell.
Beyond that there is very little resemblance.

Is there a reason that most N/A systems are done (2 X) 3 into 1 and then into a muffler?

The firing order of a six essentially means the two banks of cylinders form independent 3 cylinder engines tied to a common crankshaft and out of phese from each other. A 6-2-1 exhaust would provide minimal added torque benefit for the difficulty of fabricating an effective header. It would be a little easier using the pipe lengths of a race exhaust for engines revving up to 9K rpm.
Two independent 2-1 headers is not beneficial to a Type 4 based on the cylinder firing order.
