hey, i need some help with exhaust for a 1974 340 dart swinger. the car has the log style manifolds with the following casting numbers: 4173143-1 passenger side and driver side
4095244. They are stamped date code 84 which i believe they came off a 1984 mopar.
Question, i am looking for the head pipes to hook up a stock style exhaust system. Will the tti head pipes fit? The tti web site does not list my manifold numbers. Any advice on hooking up this exhaust system would be appreciated.

If the manifolds are from 1984, then the rest of the exhaust is probably not stock. So any headers that are for stock exhaust probably won’t fit.

thanks, not looking to put headers on. i am planning to up grade exhaust to a 2.25 system to the back bumper if it is affordable.
 
The number 4095244 comes up as a '81-'87 driver's side truck manifold, can't find 4173143-1, I "assume" it's the matching passenger side manifold. I'm shocked that the driver's side fit your Swinger. Got any pics?
You won't find pre-bent headpipes to fit those manifolds in your chassis, you'll have to find a local exhaust shop to try to bend some up.

Since you will need to have a custom exhaust made up, you really should invest in some quality headers as well. Headers plus a nice dual set of pipes will improve your performance.
 
You could buy a header-back exhaust system from jegs/summit in the size you want, for your chassis, and then just get custom head pipes to mate up with your manifolds .
