straight pipe catalytic converter
What will happen if I replace the stock catalytic converter with the straight same diameter pipe. There is still a mounting place for the O2 sensor. The headers and intermidiate pipe is stock and catback exhaust. Will it decrease the performance of the engine.What are the noticeable negative changes.

depending on the model of your car ...
1. you won't have a place for your O2 sensor
2. even if you did, you'll blow a CEL every time.
3. they're illegal
4. you'll "gain" 1hp if you're lucky.
