Crafted from 304 stainless steel with a universal M18x1.5 female thread, the kit includes the bracket, flanges, gaskets and hardware required for a complete installation. It fits exhaust tubing from 2-1\/4\" to 2-1\/2\" (57–63 mm) and is intended to create a tight, leak-resistant port for aftermarket oxygen sensors and extenders.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the clamp-on design make installation easier?\u003c\/h3\u003e\n\u003cp\u003eThe HEBRAR adapter eliminates the need to weld a bung to the exhaust, saving time and avoiding heat-related damage. You drill a single 13\/16\" hole, position the clamp around the pipe, and fasten the included bolts and nuts. This approach is reversible and suitable for hobbyists and garage installs.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eNo welding required — attaches with two bolts and nuts.\u003c\/li\u003e\n  \u003cli\u003ePre-machined flange and crush washers ensure sealing.\u003c\/li\u003e\n  \u003cli\u003eSimple three-step install: mark, drill, clamp and thread sensor.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this adapter prevent exhaust leaks and sensor instability?\u003c\/h3\u003e\n\u003cp\u003eThe kit includes a gasket, crush washers and a removable sensor spacer to reduce the chance of exhaust leakage and to stabilize the sensor.
