The stock exhaust manifold is very restrictive and cast iron. Looking for shortie headers for the 6.4L 2020 2500, what will fit?

Someone mentioned its same as 5.7L, but when looking up shortie headers for 1500 it specifically says wont fit 2500 6.4L?

Don't forget to do the tune or the exhaust won't help much. I've heard people who installed headers without a tune said it hurt performance.

Yes, anything that free flowing requires it, even just shorties with stock cats on 5.7L requires 4% fuel
