i have a small block chevy and stock exhaust manifolds. i had an exhaust shop run me a 2.5 dual exhaust with flowmaster super 40's. sounds amazing but lately when i let off the gas(manual)it makes this loud popping noise and it sounds like a gun going off. im lost on this one. any toughts would be great.
i am putting a new dist. on it tomorrow and ill double check my firing/wiring order.
any ideas.
it didnt do it at first, started like 8-10 months after the exhaust was done if not a little later.

A hole in the exhaust is my guess.
