Definitely doesn't need to be coated. The CEL can be turned off, it's passing emissions that is sometimes tricky. However the Kooks "Green" Cats are emissions compliant. Headers should come with all hardware you need but most guys use the Mopar manifold gaskets for the 6.1/6.4 hemis. 1⅞ is the best size for most people yes, 2" only for cars planning on high boost.

Also don't forget you will need a tune 100%. So factor in an unlocked PCM and programmer and custom tune. Anything more than $1000 for install labor is insane imo. $600-800 is a good price for labor.

You are in California, correct? Long tube headers won't pass smog. A new car purchased in California has 8 years before requires a smog check, so you have 8 years to play if you go this route
