Head pipe for 62 lancer?

hey there, was hoping to hear if any of you early A-body (1962ish) are running the TTI or Accurate Exhaust head pipe?
I have a 1962 dodge lancer that originally came with a 170 slant and now has a rebuilt later 225 in it, (I was told it was from a challenger) Petronix ignition, super six intake, carter 2 bbl carb. It runs really nice and has “plenty” of power but I feel the exhaust is lacking. When I measure the head pipe (not on a bend) it only measures at 1.75” OD. This is the exhaust that was on the 170 before the engine swap.
I’m a plumber, pipe work is my bread and butter and I’d love to make my own system from the exhaust manifold on but I’m really leaning towards the simplicity of just buying something that works.
Clearance looks a little tight in there between the engine mount, starter etc. I’d love to see what you have and how close it is to things.
I’m not looking for headers, just the head pipe. Pictures would be great. I’m not finding much on the interwebs. 2CD2133A-C4A5-4FC2-8DE2-0DA0834B844C.jpeg800DDB1C-1B8E-48A5-B779-665E0A1EE28B.jpeg10C37FD6-CB1A-4B16-A106-AA4F0F3DE021.jpeg84B65B1C-F8C7-4D0F-B2DB-9DAEAA7F6EFB.jpegC76FFF57-82DC-4894-8794-52F507450DFF.jpeg
I know these systems say 63- but I’m hoping it would work in my 62 with a later engine.
