I want to run the tailpipes on my 83 Cordoba 390 project all the way out to the back as the turndowns after the magnaflows is a bit loud....... I have made things much easier by getting rid of the stock gas tank as I have a 16gal fuel cell in the trunk now so plenty of room for tailpipes.

I'm thinking about using my Summit Bucks and getting some flowmaster 3" for B-body but I am not sure about the fit. The E-body ones are a 2 piece design that fit under valence.

Anybody run a 3" exhaust on their F/J/M bodies???? TBF
