Heres the problem, both my cats shredded and are clogging up my exhaust, instead of buyin new stock ones which is outrageous price wise with installation, im goin to get a set of headers and just remove them all together. my exhaust manifold is cracked but under recall, but no sense in doin that if im gettin headers...also, how do i relocate my O2 sensors so that i dont throw codes??

i need a set bad and i want to know where to get them. i dont want kspec ones
i got about $400 to spend.
I know seul has them but does anyone know about them?
