Exhaust Technology Update from Tanabe

Advantex is a highly advanced internal muffler packing material that has been developed for use in all new and current Tanabe performance exhaust systems. It is a chemically treated composite material that resists acid, heat, rust, and many other forms of deterioration. It consists of several long continuous strands of material that if unraveled, would be several miles in length. The length of the material greatly increases the lifespan of the muffler, and prevents breakdown and wear of the muffler packing material. It can also eliminate the need for steel wool center wraps to increase durability.

Advantex allows the muffler to reduce sound with less material, reduce weight and canister size, all while maintaining superior flow characteristics.

Advantex is the most advanced exhaust packing technology currently available for use in automotive exhaust systems.The benefits are so high that many large car manufacturers are switching to this material, which is helping their factory exhausts sound and perform better.

When used and engineered for a PURE PERFORMANCE application, such as the Tanabe exhaust product line, the benefits are multiplied exponentially.

The legendary low, deep exhaust notes that Tanabe is well known for is retained through our special product engineering.

 
Packing Material Types vs ADVANTEX


Fiberglass Material: This is the most commonly used material to reduce sound in a muffler. It consists of a loosely packed mat of fiberglass strands that is inserted around the muffler center.

Weaknesses: Loosely packed material quickly breaks down when exposed to heat. Exposure to water causes a chemical reaction which creates acid and rust. Pieces will break off and exit the tailpipe, resulting in a hollow muffler within a short useage life. Many times, these systems need a heavy steel wool wrap around the center to slow the inevitable breakdown of the material.



Composite Cube Material: This is used in relatively few mufflers to reduce sound. It consists of fiberglass composite cubes that require space within the muffler so that the cubes can move freely.

Weaknesses: Although slightly more durable than standard fiberglass mat pack, fiberglass cube composition is still subject to heat and chemical deterioration. Because it requires space, the size of mufflers that use this material are excessively large and heavy. Many times, these systems also need a heavy steel wool wrap around the center to slow the breakdown of the material. Cubes will shrink with time, and lose the ability to reduce noise.

 


Stainless Steel Wool Material : This is very old muffler technology that is used in a wide variety of mufflers for the reduction of sound. It consists of tightly packed stainless steel strands.

Weaknesses: Stainless steel wool has very good properties for durability against heat, but has a downside of adding excessive weight to the muffler, especially if it is the only packing material used to reduce sound ouput. In a performance application, mufflers that use this can nearly weigh the same as factory equipped mufflers.
