Straight shot intake...like what is on a corvette? You have to remember this is an LS3 in a 69 Firebird with a large C&R radiator with dual fans, power steering and alternator, etc that has to be worked around. The steel 4" pipe that I replaced the rubber 90 with does have a larger radius that eases the transition from the straight section to the elbow needed to get to the throttle body. I don't have access to a dyno and knowledgable tuner in my area.
