more bottom end torque, street engines spend most of their time from 1000-3000 rpms, yes they take short blasts to 5000-6000, but really....how often?
for a spunky, fun street car...1000-4000 is where you want your best power, and when I say power...I mean torque, I could give a crap about horsepower, torque is what you want
bigger tubes are only going to help in the way upper rpm's and 2 1/8" tubes are way too big for anything under 500 cubes unless it's built for extremely
high rpm's
I have 2" Hookers, wish I would have went with 1 7/8" tubes, I also have a 3 1/2" exhaust which I'm thinking about removing in favor of a 3" or less
more is not always better esp with a internal combustion engine
my burnout video below....that's a 12:1 (yes 12:1)
468 ci spinning at 7000 rpm with 2" tubes thru a 3 1/2" exhaust
