Custom duals to y pipe

I have Clifford shorties and put a Y off of that immediately to a 2.5” all the way out going through a black widow muffler.
Yes, you can do that & did, but how LONG & what DIA."'s were/are the x 2 intermediate pipes ?? ,.& 2.5" dia all way back is V8 size: there's quite a large increase in crosssectional area going from 2" to 2.25" & even more going up from 2.25" to 2.5" ..Sure you'll get a bellowy exh note , do you want just as we used to say: " All blow, but less go..." ?? ( not raining on your parade if you're happy ) only thing with the Clifford 'Shorties' is the big mismatch from the primary tubes merger to the too big, TOO SHORT Collectors - there's no real science involved, more fitting convenience + the primary tube area to collector tube AREA is such s FLOW MISMATCH. IF you opened up those headers it'd make the right noises but hazzard an educated guess it would be be flat as pancake with topend misfire...there's a GOOD reason why the LONG TAPERED COLLECTORS are on mine...
But hey, I won't lose. Sleep over it, but reminds me of the Hooker super competition headers with their big tube (So it must be good) with generally mismatched primary tube to collector dia ratio + their high price ( Which MUST make them even better right ??).


NB: Check the COLLECTOR DIFFERENCE BETWEEN CLIFFORD BLACK & MY RED SET: The pipe Dia", with 2.5" Tube Bolted on, Would have the gas's Velocity especially in the low end driving range, eg 2
92:1 diff's, would have gas's speed falling on its face - I would taper that big TOO SHORT OVERSIZED Collector down to 2" outlet (& tubes Dia ") with maybe set like in pic example. Which can be had in 2" dia outlets....
