I have a friend that's looking for a muffler shop in the central ohio region that can bend 4 inch pipe. Does anyone know of a shop that does. My calling around has found only shops that bend up to 3 inch pipe. Thanks in advance

 

might try a diesel shop.

 

Probably not going to find one. You could order whatever bends you need from Grand Rock, they're in northern OH.
