OK so I've been told by person here and there that for a 95 Celica GT, if I put headers and a catback exhuast on it that it won't pass emmissions. Does anybody know whats up with that? My dad and I thought up the idea that we could bore out the stock headers also but somebody told me thats not a good idea cause the headers would be to thin for the heat and it would crack or something like that. If anybody has info on either of these questions let me know. Thanks. And happy new year everyone.

it depends on your state emissions.

in california the celica has a catalytic converter built in the down pipe of the header. So when you replace it with an aftermarket header it will fail emissions.
