By comparison, 3.14 * 2.5 * 2.5 = 19.625" of total area. In conclusion, the single 5" exhaust tube would flow WAY more than two 2.5" exhaust tubes.
but.... is that necessarily a GOOD thing? seems like we may be getting too much flow.

much of tuning is like making a cake; too much of an ingredient, it's ruined. too little of an ingredient, it's ruined.

again, why aren't we seeing turbo-supras running 4-5" exhausts? i've seen numerous with 700-800hp supras with 3" single exhausts.

thoughts?
