Are there aftermarket headers/exhaust manifolds for 09 5.7L HEMI

So I'm looking at redoing my entire exhaust system and I'm having a hard time tracking down a set of headers. I have a 2009 5.7L HEMI. I've heard about people modifying the SRT headers, but wasn't sure if that works for the 09-10 WKs or just the 05-08? Do they have any sets out yet that you don't have to modify?

I dont believe they do have any aftermarket headers for our Wk's besides modifying the SRT8's headers.

The problem with WK headers is there is no way to make a bolt on effective header to bolt to the factory down pipes. There is room for upgraded shorty headers, one guy on here had a custom set made. OEM SRT 6.1 headers fit fine and they are a shorty design. The factory WK 5.7 headers are terribly inefficient and are designed this way because of the tight fit. Reviews are that headers can provide a significant amount of performance due to the poor design of the OEM headers.

You have 3 options, 1) have a custom set of headers made and modify the down pipes accordingly, 2) modify OEM SRT headers for EGR and modify down pipes accordingly, 3) modify aftermarket set of SRT headers for EGR and modify OEM downpipes accordingly or modify accordingly the downpipes supplied with the new headers.

No matter what there will be work involved to get headers on the Jeep and an exhaust shop will be needed unless you have the tools for exhaust work beyond just bolting things on.

But the cheapest option will be the factory OEM SRT headers if you can score a set for cheap.
