Dynomax Stainless Steel band-style 3" (76.2mm) exhaust clamp.
This Walker band-style exhaust clamp gives you a 360° degree seal that won't leak. This particular style was created to "butt-joint" two pipes of the same diameter together--without the need to fit one pipe inside the other.
The clamps come with pre-attached hardware and Grade 8 bolts for high strength and temperature durability.
