Need to replace original exhaust system. The truck was built according to California emission regulations but I live in New Hampshire. Can the exhaust system be replaced with any aftermarket system that fits the truck or does it need a special California setup in order to run properly? Thank you ---

I’m just guessing the exhaust system is the same. To meet California requirement being in engine differences. An independent muffler shop could probably tell just by looking at your truck. ---

My guess is the only difference is the cat for California cars has been certified to meet their standards.
