Porsche Exhaust Clamp - VNE 4014503

Product Information

An exhaust clamp is typically made of aluminized or stainless steel and is used to secure sections of an exhaust system together, keeping the pipes tightly connected to prevent exhaust leaks. They are sized based on the diameter of the exhaust pipe and are specific to the size of the exhaust being used.

The most common style of exhaust clamps on European cars are band clamps, which provide a wide area of clamping force and are robust and resistant to failure due to corrosion or rust. In more performance-oriented or high-end settings, V-band clamps may be used. V-band exhaust clamps pull two rimmed flanges together and clamp down over the top, making a very strong and tidy connection that is both easy to service and perfectly even. Finally, U-bolt clamps are a simple style of exhaust clamp consisting of a U-shaped bolt with two threaded ends, a bracket with a radius of the exhaust pipe, and two nuts. This style is usually used in making repairs in an aftermarket setting but is not typically found on OE assemblies.

Exhaust clamps generally need to be replaced if they become too rusty to reinstall, which often affects the threaded portions the most. They may also need replacement if they are bent or damaged during repairs, or if the exhaust system has been modified with new or different style parts.

• Rust: The most common reason to replace an exhaust clamp is rust. They are directly exposed to road grime and salt, and are usually the first things on the vehicle to rust. Typically this means they have to be cut off rather than simply unscrewing, requiring a new clamp for installation
• External impact damage: Because they are on the bottom of the car, knocking them on something like a rock, curb, or trailer is possible, especially on lowered vehicles. Be careful when installing exhaust clamps that you don’t allow the hardware to dangle too far downwards, which increases the likelihood of damage.
• Twisting or metal fatigue: If the exhaust clamps aren’t torqued properly, you might fatigue them with the normal movement of the exhaust system, creating leaks or tears in the clamping area.

About VNE

VNE GmbH was founded in 2001 by Volker Natorp in Hamburg, Germany. Volker has a long, storied history in the automotive field. He began his career in the 1970s working for Wulf Gaertner and in the 1990s eventually branched out on his own to start his own sales repping agency. During that time, he represented TMD Friction (Pagid/Textar) and managed all of the North American sales for them and eventually added Schaeffler Automotive to his roster.

In 2007, VNE GmbH relocated to Ganderkesee, Germany and was renamed VNE Automotive GmbH & Co. With continuous growth, the decision was made to solely focus on developing VNE Automotive and, in 2014, the focus became reality with the commissioning of a new warehouse and office space. Today, VNE Automotive prides itself on never having followed the aftermarket trend. VNE Automotive operates in a highly specialized, niche product sector, by only offering OEM automotive spare parts to more than 50 countries worldwide. This is evident from the unique, and sometimes hard to find, product groups spanning engine management, body electrical, and brake systems.
