Exhaust Questions

Ok I’m building an exhaust for my S15 SpecR and my questions are
What is the best diameter to use?
Is there meant to be a sensor near the cat mine has been removed and there is no sign of a sensor?
And is the dump pipe, down pipe and cat replacement pipe the same as the S14?
Many thanks in advance

1. "Best" diameter depends on how much power and ground clearance you want. Mine is 3 inch for example and is perfect for me.
2. There is no sensor near the cat.
3. Do some research look at part #'s from exhaust companies.
