cat/test pipe ?
I need a new cat on my p10. I am not required to do emissions in my area. Since the car is a daily would u bypass the cat and run a test pipe? Will i have to have someone weld in the 02 bung? Im guessin yes. Or do they make test pipes for these cars with bung in them? I looked on ebay and saw some but it did not look like my 02 would go in.
