duels on stock 225

Occurs to me I answered a question other than the one that was asked -- I posted a recipe for a 6-into-2-into-1 system, which is optimal for most purposes; you get a giant benefit from the Dutra Duals without drawbacks of duals all the way to the back of the car. But if the goal is maximum (or particular) exhaust sounds, then basically just do the same thing except delete the wye connector and × 2 on the pipes, muffler, resonator, tailspout, etc. A \6 through duals without a crosspipe sounds very "rappy" up through the gears, which is fun (until it gets old).
