Invidia 2015+ WRX/STi 4 Door 80mm Single Outlet Full Titanium Cat-Back Exhaust

Features:

• Full Titanium construction
• 80mm Single Outlet design
• Reduces back pressure and turbo lag
• Increases throttle response and horsepower
• Improves performance and weight reduction
• Enhances exhaust sound

Invidia exhausts are engineered to optimize performance while minimizing weight. Crafted from 304 stainless steel, these systems offer durability without compromising on weight savings. By installing an Invidia exhaust, you can expect improvements in horsepower, overall performance, weight reduction, and a more aggressive exhaust note.

Exhaust upgrades are an excellent way to enhance your vehicle's aesthetics, sound profile, and performance. As one of the first recommended modifications for car enthusiasts, replacing the OEM catback with an aftermarket system like Invidia's can significantly boost your car's horsepower, style, and sound characteristics.

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
