exhaust help??

[MyFastsPast]

Im tryng to find a place to buy a resistor to trick my o2 sensor into thinking I have a cat when I dont. In 2 weeks im getting a 3" turbo back, no cat,no resonator to flowmaster muffler. Please help? Thanx:dj:

If your O2 sensor is before the Cat, just cut out the mount and re-weld that into the straight pipe.

radioshack has resistors.

I don't know Mk4's much anymore. Unless it was a mod I did to mine.

There was also a trick I saw in the Tex about putting a spacer in there... something about moving it away from the flow....

A couple of tuning companies also have 'test pipe' files... I know APR does, which will eliminate the CEL.
