exhaust size???

Re: exhaust size???
not enough room before the cats. and Im not sure 2 cutouts in the y pipe offer any more performance than one near the rear before it goes into the muffler.
when I had a 98 z28, the one cutout gave me between 1-1.5mph at the track. car was mostly stock, other than a lid, flowmaster muffler (in stock exhaust) + cutout, free ram air mod, ngk plugs, smooth bellows, ported maf, and 4.10's.
