I guess different experiences in different situations I've done Maggies and Whipples on over a dozen cars/trucks and have gotten better results from the 1-7/8" and 2" headers over the 1-3/4. Mine will be the first Camaro I've done. I usually am running modified Maggie TVS2300s (phenolic spacers, porting, modified for boost control). I may try a dyno comparison myself.
