Hey guys

I'm having a problem with my 2003 bmw m3 Click image for larger version

My check engine light just came up again..I recently replaced my oem headers with used ones about 6 months ago because my catalytic converters were gone..my car has been sitting for like 2 months I haven't drove it, now the light came back on and my mechanic said the catalytic converter bank 1 has to be replaced again...but I was wondering if they might just be the sensors that are bad


Also another question..how are eBay headers? Would they give me a headache if I install them

Clear the codes, drive the car and see if the codes come back. The O2 sensor(s) might have to replaced if the codes comes back.

For ebay headers I'm not sure how it is on M3's but for non-m's O2sim has to be used in most cases.

Ebay headers are hit and miss for fitment but generally provide the same amount of gains as any other non stepped header. If you want cats, you can buy them for ~$100-150 usually and then weld them into your section one.
