Shortie headers 1973 Dodge Dart Sport 318 Anyone using?

Anyone using Shortie headers or Jegs 555-30500 Exhaust/Muffler Kit.

I am wanting to use shortie headers since I have a set but I am not sure if they will fit. They were made for 318 Dodge and they fit the heads in the engine on the stand fine. Looks like I may need to use a remote oil filter setup because the Pass side will go right past the filter.
The drivers side is a whole other issue with Power steering and all that mess.
I am either going to use manifolds of some type of shortie headers. I do not like the long ones.
I am also looking at the Jegs 555-30500 pipe and muffler kit. Anyone using this kit and if so how is the sound? Mild or loud? I was told that it is actually a Thrush Turbo muffler.
Please try and keep the comments and suggestions on subject if at all possible.
THANKS

I think this is like the ones I have:

Here is the situation: I already have these and they are 304 S/S. I would really like to use these and just want to see if anyone has ever used them before and if so how much sweat and blood was involved. If I can find someone who has it saves me some time. I have a tig welder so I can see a cut and weld in the future. Thanks to all.
