so my car just failed smog! first it failed inspection, cause i have bassani hi-flow xpipe and it only has 2 cats. he says it has to have 4 cats like from the factory. the hydrocarbons were slightly off, but he said if i had 2 other cats welded in before the hi flow ones, it should pass no problem. what do you think? and if so what cats should i get? i have 30 days to get em installed and retested before i get bent over for another $50.00
