Hi all, I'm slowly inching towards the final day for state inspection, and I already bought a MSA exhaust, (which will be here tomorrow) But I was going to get the header pipe 2 into1 and the next one back Ceramic Coated, but I also have on the car now, the resonator which takes the place of the Catalytic converter on Federal cars like mine, but should I replace the resonator ? I'm not saying I can even find one, but should I replace it ? This picture just shows the front half or it, and is it worth it to ceramic coat the shielding as well ??? Thank you !
