Tail Pipe Dia: '54 Super

[Fr. Buick]

What is the proper OD for the tail pipe for my '54 Super?

I picked up a NORS muffler and NORS pipes from different sources.

The front pipe, between the Y-pipe and muffler, is 2.5 inches and fits fine.

The tail pipe that I was sent is only 2 inches, but the outlet on the muffler seems to want a 2.25.

The old system on the car now is all cobbled together, so I have no idea what is correct.

So, Buick fans, do I need a 2-inch or 2.25 for my tailpipe? I like the bigger dia., but that means having my muffler guy fab something new.

Thanks for any help...

Monsignor,

The end of the tailpipe on my Roadmaster's measure 2" ID.

J.C. Whitney and Warshawsky back in the 1950's-1960's used to advertise "reducers" or "step-ups" to change pipe sizing from 2" up to 2.5" or versa vice from 2.5" down to 2". Haven't seen a J.C. Whitney or Warshawsky catalog in years. Are they still in business?

I'm sure there are AutoZone, NAPA, or other stores that sell these for a couple of bucks.

Good luck and God Bless!

The original muffler had a 2.5" inlet and a 2" outlet. Lamar is (of course) correct that the tailpipe is 2".

I actually just bought an NORS glasspack for my wagon that is 2.5 - 2".

Well, here in Norway the Big series Super and Roadmaster takes a 2 1/4" tailpipe and the smaller series 2" in 1954. The mufflers have different part number, the clamp and the hanger also. The mufflers often had a outlet that could be cut off for model adaptability (Buick parts product info Bulletin 62-1, according to parts catalog March 1, 1962).
