What's the exhaust flavor of the month? 4 to 1 collector, 4 pipes, crossover?
Here's my setup: RV-7, IO-360, forward facing Superior sump with AFP FI unit and Sam James Cowl.
I'm in contact with Vettermans and they have both a 4 pipe and crossover that fits this combo, but figured I'd get more input if possible.
.....Where did I set my magic 8ball/decision wizard?...anyone seen it?....
