Is it the mid pipe or the cat?

What will likely be different after swaping it in? More Smoke/Emission? Louder exhaust note? Smellier smog?

And how much HP am i expected to gain at the crank? just by this test pipe...

Test pipe is a fake Cat...only thing you will gain with a stock engine is a louder sound plus a ticket.

Also the exhaust smells like **** too.
I'm using a y7 mid pipe on b16 (for now)
and there is no cat on it. Smells horrible.

yeah having no cat will only yeild a few hp at most and it will make your car WAY louder, but not in a good way.
A test pipe is just a piece of pipe with 2 flanges on it to bolt in place of the cat, its stricly for track use only, then when you get home from the track you can bolt the cat back in...hence the name test pipe. IMO its not a permanent thing.

Loss of backpressure may lose power in lower end.

wouldn't a test pipe on the street result in a $300 ticket?

holy****, then i better forget it. And like what you guys saids, it won't pass smoke test for sure.

depends....my mom is still pimping her 1983 Pontiac Gran Le Mans with a 305 V8, since she doesn't have to do Ontario Drive Clean no more, she re did the exhaust and isn't running a cat

but for the rest of us....i think it's illegal....lol

depends on the year of the car if you need a cat or whatnot.. and yes its totally illegal to run with a test pipe.. ticket and your car impounded.. and it stinks..
