Advantex is a highly advanced muffler packing material that greatly excels over other packing material types such as loose packed fiberglass mats and composite cube types. Advantex internal packing material allows the muffler to reduce sound more, with less material, while maintaining extremely high flow characteristics.

Tanabe was one of the first Japanese aftermarket companies to create full SUS304 stainless steel exhaust systems many years ago. The highest grade SUS304 stainless is used on all systems for maximum durability, as well as lightweightedness. Our experience in developing SUS304 systems has allowed us to reach a high level of craftsmanship in this field.

Specially engineered for use on our exhaust systems, a piping wall diameter of 1.2mm was developed, which allowed weight to be significantly reduced, while remaining durable for extended useage. The piping SUS304 piping also plays a role in sound output, as it reduces resonation and helps our systems produce their trademark low, deep tone

Because every bit of weight savings is beneficial, exhaust hangars have hollow construction to reduce weight.

Further weight reduction is acheived and utilizes through the use of pressed SUS304 exhaust flanges on portions of the exhaust system.

Minimizing bends is a goal of each custom built Tanabe exhaust system. The truest form is realized to minimize restrictions and maximize useable power gains. Where necessary, the piping is mandrel bent for improved exhaust flow characteristics.

Tanabe exhaust systems are well known to have one of the most unique exhaust notes available. A trademark of the Tanabe exhaust system the extremely clean, low, deep tone that is both pleasant and aggressive at all RPM ranges. Designed for motorsports, this exhaust system is also fully streetable and is built to be under 93db when used and installed as a factory replacement exhaust.

Tanabe is the first and only Japanese exhaust manufacturer with a dedicated USA division to have the ISO9001 quality manufacturing certificate . Because of the extreme difficulty to obtain this certification, those who have the Tanabe exhaust system drive knowing they have one of the highest quality, most thoroughly developed systems in the world. Fitment and function are always flawless, and each exhaust is fully supported by the Tanabe USA staff for tech and warranty.
