Invidia | Catted Downpipe (Subaru WRX/STI/Liberty/Forester - 5spd Auto ONLY)

Invidia Catted Downpipe For Subaru WRX/STI/Liberty/Forester

The factory exhaust will always have restrictions and these restrictions are normally highest near where the catalytic converter is found. The Invidia Catted Downpipe For Subaru WRX/STI/Liberty/Forester Kit uses a larger pipe diameter and smooth bends which allows exhaust gases to pass with fewer restrictions and turbulence. A High-Flow catalytic converter is then utilised to still control emissions for street driving legalities but with minimal impact to exhaust flow. In some cases Invidia will also offer catless versions for off-road use where every ounce of performance is required. To withstand the high temperatures laser cut cast steel flanges are used to ensure long lasting leak free reliability. This is a 100% bolt on installation for right-hand drive vehicles with no modifications or changes required. Factory O2 sensor locations are also retained where required to ensure compatibility with factory systems.

INVIDIA PERFORMANCE

Far more engineering goes in to the design of an exhaust system than many realise. From a performance perspective, there is a fine balance between exhaust back pressure and exhaust gas velocity. Too large a diameter pipe, and low down power and torque is sacrificed (particularly on naturally aspirated cars), too small a diameter or added restrictions and bottle necks in the system, and the engine is unable to push gasses out of the combustion chamber efficiently, reducing power and torque. There are many other technical aspects such as "scavenging effect" which are beyond the scope of this document, but the point is, it's not as simple as just strap on a drain pipe and gains for days. A "quality" exhaust system maximizes performance gains by design. Invidia High Performance employ a team of engineers and conduct thorough research and development for every single exhaust component they manufacture, ensuring performance to match the customer's needs in every instance, including the use of the highest quality High Flow Catalytic Converters where applicable.

INVIDIA SOUND

What an exhaust sounds like is typically the number one factor when choosing a system. The acoustics of an exhaust system are hugely complex. Many people believe that all an exhaust does is muffle the natural tone of the engine, but in the vast majority of cases this is far from the truth, in fact companies like Ferrari, Lamborghini, Pagani, Porsche and alike all spend massive amounts of time and money "fine tuning" their exhaust systems to sound exactly how they want them to. Put a straight pipe on just about any hypercar and that distinctive engine note is lost. Invidia spend countless hours on research and development, including listening to customer feedback in order to fine tune their systems to suit the target market for each model from the quieter Q300 to the Race orientated G5 Titan, so you can be assured your car sounds its absolute best, without sacrificing performance.   INVIDIA LIFETIME WARRANTY Buy with confidence!
