Exhaust systems on C1s

[L88 crazy]

I am confused as to the types of exhaust systems installed on C1s. How many types were there and what pipe sizes? How long are the mufflers from inlet to outlet? What is the difference in exhaust notes between the mufflers that came stock on C1s?

Up through the 1961 model year, all engines had 2" exhaust manifolds. The 1962 300, 340, and 360 HP versions had 2 1/2" manifolds. So the front pipes for these 2 different manifolds are different. But not so different downstream. After the first 6" they are both the same diameter. Downstream of that, the 2 and 2 1/2" versions are the same.

Some of the higher HP models also had cross over pipes in the front pipes. It is thought that cross over pipes do change the sound.

Finally there were 2 different mufflers - the stock oval ones and the "off road" round ones. They definitely change the sound.

I wish someone sold a complete 2 1/2" exhaust system for C1s, instead of having to get one custom made.
