Description, Q&A
Invidia exhausts are engineered to enhance your vehicle's performance and sound. This cat-back exhaust system for 2015+ Subaru WRX/STI models features a single Q300 rolled stainless steel tip, offering a perfect blend of style and functionality.
Replacing your OEM cat-back exhaust with this Invidia system is an excellent first modification for any car enthusiast. It's designed to increase horsepower, improve style, and enhance the sound of your Subaru.
Invidia High Performance employs a team of skilled engineers who conduct thorough research and development for every exhaust component they manufacture. Their designs strike a perfect balance between exhaust back pressure and exhaust gas velocity, ensuring optimal performance gains. Invidia uses only the highest quality materials, including High Flow Catalytic Converters where applicable, to meet customers' performance needs.
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.
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 bottlenecks 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
