That Megan Racing catback is a good exhaust setup. Eventually you might think about going larger, but it'll work just great for now. The OBX 4-2-1 header is an awesome header. I have it, in stainless steel. Go for it.

I was told the O2 sensor for the OBX was in the wrong place. but I need to ask chad again to be more specific.



Forever a work in Progress

The O-2 is in approximately the same place as stock, but because of the header design it only reads 2 cylinders(2&3).
If you want to have it read all 4 cylinders, you'ld have to get a stainless O-2 bung and weld it in after the 2nd collector, put an extension on the sensor lead, and plug the original O-2 bung. There is a possible problem with doing this, the sensor wont heat up to operating temprature as fast and the sensor readings may be delayed enough to cause PCM problems(i.e. reading A/F ratio later in the operating cycle).
BTW: Any one out there done this mod, have any problems?

yea it only reads 2 cylinders, but it doesn't cause malfunction.
