+650HP 997 TT (Sound Version) Stainless Steel Exhaust System_x000B__x000B_The +650 hp FVD Sport exhaust system is specially designed for vehicles with performance increases of more than 485kW (650PS). Back pressure is extremely reduced trough specific guidance and piping in the exhaust muffler._x000B__x000B_- 200 HD Cell high flow, tri metal German HJS sport catalysts _x000B_- 2 3/4" tubing (70mm) straight through design for max. Power_x000B_- Weighs 39 lbs. (18,1 Kg) _x000B_- T 316 stainless steel for improved durability over T 304_x000B_- Cone style catalytic connection design to prevent exhaust leaks_x000B_- Includes quick release clamps_x000B_- Made in Germany _x000B_- DME programming necessary._x000B__x000B_We use the latest HJS cats, they are nicknamed ?HD? for high durability matrix design catalytic converters. They have a SM-matrix (winding of three flat and corrugated foils) and a special connection to the matrix sheath, which equates to extremely high durability for track and street use. The added benefit is that they DO NOT generate catalytic efficiency codes (CHECK ENGINE LIGHT) that most OEM Porsche programs (EU 5 software) generate. HD cats are perfect for those who want to run sport cats without a software program._x000B__x000B__x000B__x000B_Please Note:_x000B_Exhaust tips are not included! _x000B__x000B_Using stock tips on our sport mufflers without FVD tips will cause Hp loss. Once you restrict the diameter of the piping a small percentage of power is robbed._x000B__x000B_Our tips are 3" diameter (75mm), same diameter tubing as our muffler systems. They are "quad" 3.5" (90mm) tips and are made for this muffler. Kindly order tips separately._x000B__x000B__x000B_FVD is proud to introduce our newest line of Brombacher exhaust systems. Brombacher exhausts are engineered for the discerning PorscheÆ owner and offer unmatched performance, unparalleled quality, and incredible value. All of our exhausts are manufactured in Germany and are tested comprehensively for flow rate and characteristics, thermal stress, resistance to cracking, and longevity. To further ensure quality, all of our exhaust systems meet the standards of the German independent testing agency T‹V; whose quality standards are among some of the strictest in the world._x000B__x000B_Brombacher mufflers outer shell dampens and eliminates unwanted frequencies and ensures no resonance or drone in the cabin. The end result is a strong, linear, firing-order dominated flat-6 PorscheÆ sound. In addition, Brombacher exhausts systems are available for ultimate performance full titanium. Our titanium systems are nearly 40% lighter compared to steel and are available for late model, water cooled applications. Each of our exhausts have been extensively tested on both a chassis and engine dyno as well as logged thousands of miles on both the street and at the track. All this research, development and testing ensures maximum horsepower gains throughout a broad power band; all while maintaining reasonable sound levels for the street and provide a distinct, sporty exhaust note that is purely PorscheÆ._x000B_
