Calling All Mechanical Geniuses

I do not desire to debate anyone, but the easiest way to remove ALL the backpressure on an engine is to:

(eight) Adequate Sized (for the air flow) Individual pipes, non-baffled, exiting as close to the head as possible.

A properly designed and sized exhaust system with an X pipe has been proven to make more power than open headers....I can't remember which magazine did the power comparison, but it was clear as day after reading that article.

A properly setup X pipe system scavenges (pulls) the exhaust flow from each bank and is not choked down with too small diameter pipes.

For a lumpity 360, I would use headers or good manifolds, Dual 3" with X pipe and straight through design mufflers...made of T304 Stainless for longevity and durability.

just IMHO (in my honest opinion).....
