Just got the factory cats off the car and only broke one Bolt on the Passenger side. The DIY helped alot to tackle those from the engine compartment first. Just needed $50 more in tools, but you can never have enough.
So the CNT test pipes are in my hand. I plan on putting the plug in the forward bung hole near the headers and using the extended tube near the middle for the O2 sensor. The hole inside drilled into the exhaust is only 1/4 diameter and not the full size of the bung hole threads (about 5/8").
Do I drill this out or leave it alone? I am not a mechanic, but pretend to be one on Father's day.
I can't wait to get that factory exhaust off the car!!!
