gold95sl2

Okay so I used to have a 95 saturn sl2 but sold it. Now I have a 97 sc2. I transferred over, from the old saturn, my header/down pipe and high flow cat and custom 2" cat back into my greddy muffler...

my problem is that this newer sc2 has 2 O2 sensors, one in the header and one after the cat...

I need some advice because my check engine light will not shut off since the new exhaust system...

after spending over $200 to get the system to sound how I like it... is there anything that I can buy and put on/ in the system to increase restriction so the "too free flowing" problem and the check engine light go away while still keeping the good, loud sound?

thanks guys!

What is the code that you are getting?

well...
the guy at the local auto zone pulled the code.
he didn't tell me the number of the code but he said it pulled 2 codes.
1. O2 sensor malfunction
2. Multiple misfires within the spark plugs (this one may be old and n/a because i changed the plugs when i bought the car 3 weeks ago)

the first one i understand could be from the free flow of the exhaust but that is what stumps me...

thanks for the response!
