you probably need to change your catalyst or your o2 sensor. have your car checked up with an obd sensor to see what part you have that are flawed.

The catback is just piping and a muffler. It has zero effect on emissions. It may cause you to fail the inspection part, depending on how strict they are in your area.

The only thing in the exhaust system that has effects on emissions are the catalytic converter and the primary o2 sensor.

dc2: so the holes in the piping will only cause me to fail inspection?

either way i need to replace the catback, and im looking to upgrade and help performance.
