for power wise nit really much, untill you start to put alot of mods on your car, but **** is it loud man, espically if you have a full cat back, it really start to get annoying after some time.

there's no point in using a test or straight pipe if u've got a stock engine, let alone SOHC. Even w/ a stock B-series, there won't be a significant gain. If anything, you'll lose backpressure and torque in the lower range.

But, if you're using forced induction, a straight pipe is the cheapest way to get more power.

However, you'll get a hefty fine for having no cat in the streets.
the best thing to do is to fabricate a fake-cat.

and in terms of how loud it'll be, it depends in ur mods.
stock- it'll sound like a fart can
200+hp- thunderous
