Review on High-Quality Vibrant 1171 Exhaust Sleeve Clamp: Pack of 1, Silver - Ultimate Performance Guaranteed! by Aaron Jones

My OEM clamps on my 13 Camaro ZL1 looked exactly the same (even with the same stamp on them) except they had nicks. This was for an OEM link that had a small post about factory cats. After switching to long headers and high flow rolls I no longer needed that notch and it allowed the exhaust to flow out. I received these clips and they were exactly the same but without the notch. Eliminated the exhaust leak, happy with the purchase. It's a strong thick metal unlike some of the cheaper clips I've used on other vehicles in the past.
