When restoring and enhancing classic GM vehicles, we tend to prioritize the exterior, engine, and interior aspects. However, one vital component that often goes unnoticed is the exhaust system. At Original Parts Group (OPGI), we recognize the critical role a well-maintained, high-performance exhaust system plays in classic cars. While OPGI offers restoration and performance parts for various GM classics, today, we’ll focus on OPGI’s exhaust options using our 1966 Pontiac GTO as a prime example.
