I have a 3in inch custom exhaust straight pipe and the DMV hit me with a dang smog check!! smh.. What kind of catalytic converters can i weld in there and what else do I need to pass smog? Can anybody help me out?
I would try to find a stock exhaust to bolt up for the test then you can change back. Unless you permanently want to weld in a universal 3" high flow cat.
