I need help. I bought a spec'D tuning catback exhaust system along with a test pipe for a civic. Also bought headers for the b18b1 engine from a integra yet it seems that the test pipe is short and doesnt quite reach the test pipe. In replace of the test pipe I am looking for a catalytic converter but i need advice on purchacing one. And I need to buy a speed sensor, im guessing, because my speedometer is not moving at all when the car turns on or when moving. Thanks guys if u have any advice please feel free to tell me thanks.
