What size tubing to match 1 5/8 header?

[aston@ultrasw.c]

I am installing 1 5/8 headers onto a basically stock 3.2 motor.

I will be fabricating a dual exhaust system, with 2 cats and mufflers. I plan to use magnaflow components.

So what size tubing should I use to match the header?

TIA

How about 1.675"?

you should use 2" from the flange back on both sides. This is what is typically used
