Looking at buying the flowmaster American Thunder 2 1/2" exhaust. All the company's only show for 67-74 a bodies. Can't seem to see a listing for my 75 duster? Should be the same layout I would assume. Or any other recommendations on exhaust welcomed. It has a 360 in it. Thanks
 
Should fit with no issue. I had a muffler shop make up an exhaust on my 1975 dodge dart sport. If doing it again would have gone pre bent.
 
No listing for 1975 may have something to do with the start of catalytic converter use by the factory.

Weren't the floor pans different to provide clearance and required different seat tracks?
 
Although that kit will fit a '75, advertising as so will land Flowmaster and Pypes in hot water with the Feds very quickly. Pypes makes systems for the A-Body, in both H and X-pipe configurations. You also have a choice of 4 different mufflers.
As correctly stated above, you will need long tube headers as nobody makes SB downtubes for the A-Body.
Do your homework on the sound you want. FM American Thunder is loud. So is Pypes Violator. Street Pro is moderate and Race Pro is on the quieter side. Their new Turbo Pro muffler is a copy of the Dynomax Super Turbo and is and awesome street muffler.

TTI makes down pipes @ 2-1/2 inches for the exhaust manifolds to connect to there exhaust system. You will need the numbers on the exhaust manifold so they can be sure to get the angles right since exhaust manifold design will have the outlets at various angles and locations.

Rumblefish360, thanks for that info. I know Pypes is looking for a volunteer to have downpipes made for the A-Body. Question- how many variations are there for A-Body manifolds?
 
...and which design has better clearance (and clearance for what, column linkage, floor linkage, manual linkage, etc)

That is a great question I can not answer off of the top of my head. I’m not even sure I have a book that could, but, I’d bet the interchange book would carry that information. It covers mostly the muscle gears of all engines, trans, rears, brakes, etc... parts of the car with casting numbers and what is and what is not swapable between years makes and models.
