7* retarted will make a big difference. btw i have 3" exhaust and a walbro on my stock ka24de (getting ready to turbo) and my car runs 15.5 in the 1/4 but i think 15.4 is possible. enough of this exhuast backpressure bullshit. backpressure is NOT needed in a n/a motor exhuast velocity is needed to a point but that is taken care of through a well designed header and collector.
