Catless downpipes are turbo whereas us Gen1s are supercharged. If you do have a turbo, suggest you post in the Gen2 section.

You need to tune the car, and have the secondary o2 sensor tuned out.

Spacers and simulators don't work, you'll have a CEL return at some point in the near future.

I use a spacer with a catalytic converter in it, because I'm too lazy to get a bung installed after my highflow cat
