Exhaust on a turbo
I know that on a turbo car you need at least a 3" diameter pipe. Is the pipe gonna be from the catalyc converter then straight back? Or do you eliminate the cat. And I assume it has to be a straight pipe correct?

it could be from either one. If you elminate your cat, you have more straighter airflow which makes your exhaust free flowing. Also by elminating your cat you gain power up top but lose some down low.

As for the exhaust, the minimum isn't 3". Sometimes that is too large for the amount of boost you are running. 2.5" is probably more ideal for running 6 psi. Higher boost is for 3" or maybe even 10 psi.

I am probably running 5-8 PSI so a 2.5-2.75 pipe would be ideal right? I here its gonna pull a CEL if I remove the cat. So is it really must? Or can it still work?
