whats the best way to make power?

[jam]

whats the best way to make power I am running 2.5` exhaust straight with racing decat and no backbox (silencer) or other option taking out decat add a blitz nur back box? Is backbox nessary on high bhp engine. Which is the best to produce more power on drag racing 400mt run.Thanks

with a turbo car, you dont need to rely on back presure, theres alots more air being sucked into the engine and a n/a car, so the the quicker you get the air out the better, so i would not worry about what back box to have to much

if you look at the front of the exhaust were its bolted on the decat your see alot of exhaust narrow down to like 2 inch then back to 2.5 cut this off and reweld the flange thats a improvement as it restricks the flow a turbo would be a good upgrade or engine managment system bud
