Flowmaster Exhaust System

Buster Joe March 10, 2022

I installed the Flowmaster Exhaust System on a 1972 Chevelle to a set of Doug Thorley Headers. Everything went together extremely well. I recommend the product. However, one of the welds on the H-pipe was missing. There was about a 2-3 inch incomplete weld. Other then that, great product!
