Once the mixture is burned and sent out the exhaust valves, nothing changes its makeup except for the cat- everything else is just metal or fiberglass muffling to keep noise down or redirect the gases under the car.
High flow cats will change your emissions if they are high-flow because of lower efficacy.

u kno, that makes sense now that i think about it.
Everything is already burned up.
I guess here is an analogy: Take a 2 ft long hose and a 30 ft long hose (shorty headers compaired to LT's) run 30* water through it (30* is "emissions") *NOT factoring in the sun heating up the hose* the water will still come out 30* in BOTH setups. Unless you add a water heater (heads, cam, ect).
do they have "normal flow" cats for LT setups?
