My car failed inspection miserably to the point where my car was given a 48 hour notice on it's emissions, (all because of my exhaust). Money is tight to just grab a stock exhaust system on but a High flow cat could help.

Does anyone have experience with a legal exhaust system? I need this to pass inspection and keep the cops off my back.

 

a lot of people are using oem s2000...itr...07 si civic..or dc5 rear end muffler...very quiet and high flow..i personally use oem s2000
or u can try apex-i sw2 cat back ..

 

do they have the catalytic converter?
and would it fit my 94 civic coupe?

 

for oem honda/acura rear end muffler.u have to have a muffler shop to weld it on..for apex-i sw 2..it is a direct bolt on ..

 

gotchaa

 

i had a fart can ona and my resenator removed and mine passed. its not super loud but its not stock silence.

 

i didn't have a catalytic converter on my car, so the noise was too high and emissions we more than three times what they should have been
