The unsung heroes of your exhaust system are the exhaust clamps, those simple yet critical devices that hold it all together - and get none of the credit. Flowmaster announces the arrival of their new Premium Muffler Ring Clamps available in 2, 2¼, 2½, 3, 3½ and 4-inch diameters. These zincplated clamps can handle lots of torque and tighten up with the twist of a single 3/8-inch, quick-to-tighten, large thread bolt. Designed to deliver years of leak-free service, these clamps are the perfect way to ensure a tight fit that will keep your tubing right where you want it regardless of the demand. Sold Individually
