I need new exhaust pipes for my RV-4...Would someone please educate me on the difference
between "straight pipes" and "cross-overs." Fuel consumption obviously
is a big concern now, and noise levels near a small community could develop
into a problem...Specifically, do "straights" enable more power from the engine,
and less fuel consumption?..Seems I read somewhere that "tuned" exhausts
were the way to go...What is the advantage and disadvantage of each?..The engine
is a Lycoming 0-320 E2A, modified to 160 HP..........Thanks..........CHEERS!!!!..........Gene
Smith.

I think Larry would tell you there is no noticable
difference between the two. Perhaps the crossover
would be alittle quieter.
You can get a larger heat muff on the 4 pipe
covering two pipes..
