The MagnaFlow Difference: Clamps

Welcome to this episode of the “MagnaFlow Minute” where we give you some quick facts about the construction or design of our product and why the MagnaFlow Difference matters. Today’s topic is catalytic converter clamps!

MagnaFlow primarily uses Torca’s AccuSeal exhaust clamps on our catalytic converters. These clamps feature a reaction block that provides a full 360-degree equal distribution of clamping force, prohibiting pipe distortion while creating a unique seal. One of the primary benefits of using these Torca clamps is that the exhaust connection remains serviceable and easy to disassemble. This allows clamps to be taken on and off with no need to resize the pipe, while also eliminating the chances of exhaust leaks due to pipe distortion.

Most aftermarket catalytic converters will be supplied with a U-bolt style clamp, or sometimes no clamp at all. Because a U-bolt style clamp applies uneven force to the pipe, tightening it essentially crushes the sides of the pipe together. If the clamp is removed, the pipe must be resized before the clamp is reinstalled.

Joints utilizing U-bolt clamps are more prone to exhaust leaks compared to Torca clamps.  An exhaust leak can create an annoying ticking sound while in operation.  More importantly, an exhaust leak may affect the proper functioning of the catalytic converter. The Torca clamp bands used on all MagnaFlow catalytic converters are made of corrosion resistant 409 stainless steel. The durability of the material prevents premature clamp failure, avoiding exhaust leaks and maintaining the life of the converter.

Alternatively, other aftermarket converters on the market use clamps constructed of mild steel. This leaves the clamps susceptible to the elements, making them a common failure point as they corrode. As the clamps deteriorate, they can become bonded to the exhaust pipe and may need to be cut off in order to be removed.

The Torca clamps on MagnaFlow converters are complete with all necessary hardware pre-assembled on the clamp. A single torque point adds to the ease of installation and adjustment, which is especially noticeable in those hard-to-reach installs.

You’ll most commonly find U-bolt clamps on other aftermarket converters with two separate torque points. The two separate torque points make it difficult to get even clamping force and installation can be more challenging when space is limited.

A tight seal is the way to avoid exhaust leaks and MagnaFlow notches all converter slip joints that are connected by a Torca clamp to allow for proper pipe deformation to seal.  The U-bolt clamps of other aftermarket converters offer a much smaller clamping surface area, providing less grip and an inconsistent seal. The larger surface area of the Torca clamp’s 1-1/4” wide band provides better grip and a long-lasting hold.

When selecting a replacement catalytic converter, it is important to consider the design and construction of the clamps. MagnaFlow uses Torca clamps for a tight, durable seal ensuring proper converter function.
