Replacement Mufflers

[John]

Hello, I have a '75 C-3 with 2 1/2" dual exhaust and turbo mufflers. After doing some engine work to add some performance to this machine the turbos seem loud. Would really appreciate listening to the radio now and then.

Here's my delema. I look at the Mid America catalog at the stock type mufflers and they list 2 1/4" inlets and outltets for the year of '75. For '78 they list 2 1/2". If I look at Dynomax they list 68-82 as the same.

The mufflers presently on my car measure 5" depth x 15 1/4" lenght. Inlet's and outlets are 2 1/2".

Does anyone know the exact measurements of the '75 verus the '78 so I can know which one will replace the one's I have?

Can anyone tell me if there is a high performance muffler that is as quiet as the stock muffler at a reasonable cost?

Thanks,

John

Re: Replacement Mufflers

John, The mufflers on 75 and later are the same size body. The inlet difference is 2 1/4" for L48 and 2 1/2" for L82. You can use a 2 1/2 " rear Y-pipe with 2 1/2" mufflers for better flow. The Dynomax mufflers have a mild idle tone, but do make a bit of roar under load. I suggest calling Allens Exhaust (219) 722-7272 if you want a quieter 2 1/2" muffler. He will make them for you. Tell him Wild Bill sent you. Good luck! WB
