Default Turbo exhaust piping...... for 225whp to 270whp .... size?

I had a question. I'm going to be boosting my 91 hatchback with a BONE stock b18c1 in it. I'll be running a small t3 turbo looking to make about 230whp at about 7-8psi daily driven. Also will be shooting for 10-12psi to make about 270-300whp.

Would a greddy sp2 exhaust (2.38inches) and a CarSound Cat be ok?
or will it be WAY too restrictive for my daily low boost setup?

Keep what you have and run with it. If you don't make as much as you wanted, upgrade.

you migh tbe running the t3 out of its efficiency range if you are shooting for 300whp... but its worth a try. I say, f the new exhaust just get an e-cutout... straight up open headers
