MBRP Universal 31/2 in ID. to 4 OD. Adapter Aluminized

Universal Aluminized Steel Exhaust Adapter (UA2007) by MBRP. Material: Aluminized Steel. Inlet Diameter: 3.5". CARB Compliant: Yes. This adapter will let you change the diameter of a 3.5" exhaust system pipe to a 4" diameter. This will simplify adding an aftermarket exhaust system, or customizing or fabricating your own exhaust.

Sometimes things just don't line up the way you want them to, and it becomes necessary to improvise. Use these adapters to change the diameter of an exhaust pipe to a larger diameter. They're swaged to slip-fit the mating pipe exactly, needing only a simple muffler clamp to achieve a perfect seal and mechanical integrity. No welding required.
