i went to the kteller website to buy a carsound catalytic converter, but there are a bunch of diiferent sizes and options. which size piping do i need if i have stock headers and a greddy evo2? 2'" 2.25" 2.5" or 3" and after i figure that out i need to know whether or not i need a 3 bolt flange, 2 bolt flange, or in- 2 bolt/out- 3 bolt flanges. im pretty sure i need o2 bungs front and rear because i had to replace both of them.
quick responses would be great, my emissions tag is about to expire and i cant renew without a new cat...
