on engines with a turbo.
What are the pros/cons of a smaller system (2.25 or 2.5") versus a bigger 2.75"/3"
please explain with as much detail as you can.
thanks alot

of course the cat. This is the drawback to a quick responding street friendly OEM turbo because along with the backpressure comes exhaust gas reversion. More heat...less boost. I don't think the exhaust size means much with these little guys, but I like the way 3" looks and sounds. On a big turbo with some decent cam overlap you got to follow Hondas lead for a race engine...4"!

but since the turbo will make more power in the higher rpms you want to make sure it can flow more exhaust up in the higher rpms.
