I don't think this was discussed before, I looked and didn't see it.
I got a set of SS exhaust pipes (straights) that are about 10 inches long for a parallel valve. They sound great on an Lycoming (and look great at night - Blue fire), but we were wondering if this would cause any problems. I was told they could lead to burnt exhaust valves by one fellow and another said it would reduced horsepower when compared to just normal headers.
Does anyone know if they could cause problems with valves or loss of HP due to less back pressure when compared to typical collector headers?
Also, does the flex pipe or even mufflers have that much impact on HP produced.
Thanks Pat
