That’s what I expected thank you for confirming that! Not sure if I’m gonna do 6.4/6.1 Headers or go with some inexpensive Long Tubes. Just thinking of ideas and pricing them out at the moment. Budget is pretty tight because I’m swapping a new crate motor into my car at the moment due to failure.They will bolt to engine -but not fit stock exhaust. Also you have square shape exhaust ports - the 6.1 is d shaped- will work but not ideal.
Sounds good! Instead of having the 6.1 Pipes connected to the stock 5.7 pipes is there a Catback or other option that doesn’t involve the connecting of the 6.1 and stock pipes?I did this on my 2010 Challenger You will need 6.1 shorty's and mids. Plus you will have to expand the mids to fit OVER the 5.7 pipes due to the differences in diameter. You will also need a set of 6.1 exhaust manifold bolts.
Ok let’s try and sort this out:Sounds good! Instead of having the 6.1 Pipes connected to the stock 5.7 pipes is there a Catback or other option that doesn’t involve the connecting of the 6.1 and stock pipes?
I have the 6.1 manifolds and mids (Solo performance 3") on my 5.7 (eagle) cat back and they fit just fine. I tig welded the connections becuause the 3" mids fit perfectly over the pipe (not inside, but outside) and I didn't want leaks.Ok let’s try and sort this out:
6.1 exhaust manifolds require 6.1 mid pipes
6.1 mids do not match 5.7 catback (this is why hemi_57 explained a method to adapt the two so you won’t need to spend $ on a stock or aftermarket 6.1 catback). You could purchase whatever 6.1 catback you want or adapt the current 5.7 catback as described by hemi_57.
If money is tight and/or simplicity is desirable, some JBA shorties (#1964) will perform similar to the 6.1 shorty manifolds and you would not need any changes to your current exhaust system.
