Side pipes only look good on a very short list of cars. Popular choices were Corvair Turbo mufflers, hemi mufflers, Cadillac mufflers, Walker Continentals, and even straight pipes with NO mufflers on many cars. Basically, it seems like any muffler with 2.500 inlet/outlet was a viable choice and that particular size pipe was considered large for many years!
