Hi Mike-

The main tubing on both cars you asked about (2345 and 2431) is 3 inch, and the "fake muffler" sections were roughly 24-25 inch sections of 3.5" tubing (most guys substitute a 3.5 inch glasspack in modern replicas)

CSX2558 was another usrrc car that also had a sidepipe configuration very similar to the pipes on CSX2431 and CSX2345...
