It’s very tight and needs to be adjusted some times as it rattles, Thinking of going back to 2 1/2 inch tail pipes so I can run stock reproduction chrome tips

It can be done with the existing 3" if you want to take the time to squeeze in some adapters.

I did something similar on our 69 Z. I wanted the factory tailpipes on the car as they are a bit unique and stand alone amongst anything seen in the aftermarket exhaust industry. The issue is they are only 2" in diameter.

I run a Pypes 2 1/2" transverse system on the car, so I grafted in a pair of mild reducers to step it down. Took some time but now looking at the car from the outside it appears it has an OEM exhaust system on it.
