Exhaust clamps, hangers and other securing devices for the muffler, catalytic converter and the exhaust pipes must absorb shock, resist corrosion and keep their connection profile. Most exhaust clamps contain certain alloys and have specific tensile strengths to keep them from rusting or breaking. A wise vehicle owner will not skimp on quality and design when it comes to replacing any exhaust clamp, hold-down or hanger for the exhaust system.

Exhaust Band Clamps

The exhaust band clamp's newer design features make it a good choice for a replacement clamp. It includes metal designed to stretch around two pipe joint seals and create a solid, no-leak connection. These clamps come in several configurations, with the better design consisting of a cinching block at the ends of the clamp that tightens until it bottoms out flush with the pipe. The other design comes equipped with a foil piece to insert between the clamp ends and then tighten down to form the seal. Both clamps come in aluminium or stainless steel construction. The aluminium type has appeal for lightweight, high-performance applications, if you must consider overall vehicle weight.

U-Bolt Exhaust Clamp

The U-bolt exhaust clamp rates as the most common standard exhaust clamp on the market today, reports the Diesel Service Parts website. Its design allows it to encircle the pipe and crimp down on it, forming an extremely tight pressure seal. These clamps rust and become more brittle than the other designs, and many times break during removal, but with a lower price than the other clamps, installing new ones on all the pipe joints can prove cost effective. The excess threads on their ends, after installation, leave enough room to clamp other devices to them.

V-Band Exhaust Clamp

The V-band clamp, also called the "turbo clamp," comes equipped with an angular groove built into its construction. The groove's design helps it sit securely around the turbo exhaust flange on the exhaust pipe. The clamp comes in various sizes, but the diameter can be a crucial decision, as you must measure the flange size on the exhaust pipe to obtain the proper fitting. Another design feature has to do with the groove angle, so you must make sure that angle will fit your flange precisely. If the width of the groove and the diameter matches up, the fit should be fine.
