ALPHA 不鏽鋼束環，碳纖維筒身，30-90-8

The carbon fiber clamp matched my existing exhaust perfectly and those stainless bolts feel solid. Installed it in minutes and everything is tight.

Finally found a clamp that actually fits my carbon fiber can without crushing it—the 30-90-8 size range covers the taper perfectly. Tightened right up with no slipping.

The clamp is machined cleanly with no sharp edges, which made seating it on the pipe and torquing it down a breeze. It grabbed the carbon can’s connection point solidly without any worry of it slipping, even after a couple hundred miles of vibration.
