Is the exhaust pipe the same size on a 454 and a 350?

The exhaust pipe size can differ between a 454 and a 350 engine, as the 454 is typically a larger, high-performance engine that may require a larger diameter exhaust system to handle increased exhaust flow. Generally, the 350 engine uses a 2.25-inch diameter exhaust pipe, while the 454 may use a 2.5-inch or larger pipe, depending on the specific application and modifications. It's important to check the specifications for the particular models involved to confirm the exact sizes.
