392 headers / improved manifolds

[nevd1430]

Curious what people are using to improve exhaust flow.

I'm looking to improve flow and curious if anyone has found headers ( other than afe short tubes). If not headers, any improved manifolds?

Would anyone know what manifolds are used on the JL hellcat swaps? These might be a option. Thanks to all.

This is about all I have found so far. https://www.jeep392.com/threads/afe-headers.1814/ Would like to see a nice set of longtubes.

Same. Looking for long tubes or curious what was used on the hellcat swaps before the wrangler 392 manifolds were available. The short tubes don't seem to add any additional HP.

Yeah, they never really do. Todays manifolds are pretty hard to beat. Only longtubes and a good tune.

I think most of the swaps use factory headers, it’s the headers back that they change out.

i wonder if new headers will eliminate the 392 cold start chirping noise
