Gene, Go with the Vetterman straight 4 pipe system on the RV4. It's painless, efficient
and allows the greatest HP from some comparisons I did early on. It has
served me well with no cracks or problems in 1500 hours...

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
