Note: All CC '63 exhaust systems have a "kick" to clear the floor tool tray. We believe that all 63's except possibly very late cars (unverified) were delivered this way whether early or late.
* Original factory exhaust systems came on the car with the secondary pipe welded to the muffler. The chart above lists systems both with the welded mufflers and with the muffler pipe separate. NOTE: This system is not to be confused with the O.E.M. high performance "off road" exhaust system which also came as a welded secondary pipe and muffler assembly.
** These systems are available with our Magnaflow Hi Flow Mufflers. To order add $35.00 and specify - Mag Example: 322635-Mag = 64-65 2 ½" Exhaust System.
63-65 Exhaust Bend
We received our "original sample" in the mid 1980's from a customer's Hi-Performance 1964 Corvette. We never questioned its originality, due to the condition of the part in relation to the car.
Over the years, we had a few complaints regarding the fit on the left side of our systems, but we double-checked our fixtures and bending procedures and could never pinpoint a real problem. In late 2007, a customer contacted us after receiving a new system for his 65. He claimed that the left header didn't fit right because it didn't match his original pipe. The following week, we had his original pipes in our shop. We could actually make out the original part number and there was one small bend at the end of the pipes which changed the whole attitude of the secondary pipe. We changed our bending program to match the new sample.
The customer did the install and checked the fit for us and we believe we have solved the left side fit problem on 63-65 systems. This mainly affects the welded type OEM systems, and it is easy to overcome this problem with an independent pipe and muffler. Those same fit issues on the left side pipes will occur when installing new off road secondary pipes using old CC headers. So, unless you're sure of what you have, a new system is the way to go.
