i drive a 1996 auto civic dx and my friend gave me a straight pipe and put it in for me for free and kept the OEM exhaust. it was free so i just tried it. But my question is How can i pass emmissions cause i got no cats? i want to get a new exhaust and keep the sraight pipe. Do i get a HIGH FLOW CAT?

 

BUMP!!!

 

anyone?

 

You need a cat to pass emissions. Are you throwing a check engine light ? If so, you may be running in lean mode. It probably sounds ridiculously loud right?

 

I dont think you will pass emissions with out a cat. and still a high flow may not make it.

 

why do anything to an automatic, save up and get a manual conversion. and unless if you got a big turbo, or a buld na motor, a test pipe wont do **** for you but make your car sound like ***, mess up your O2 readings, and make you feel like your driving a "fast" car
