The PSR O2 Turbo Outlet is the last piece of the puzzle needed to give your Evo X a complete turbo-back exhaust system. This is a direct bolt-on addition to the factory turbo (or factory replacement turbo) and connects flawless to the Invidia catted Front Pipe. 100% Stainless Steel construction for long term performance and durability.

INVIDIA Q300 CAT BACK EXHAUST

Tuned Muffler - For optimal flow and enhanced sound

Invidia's Q300 tuned muffler systems provide a quieter exhaust sound than both the R400 and N1 Invidia Exhausts. While still keeping volumes in check, their high flow design ensures efficient exhaust flow for optimum engine performance and prevents sacrificing any increases to power or torque. The Q300 mufflers offer a rich, deep, sporty exhaust note which enhances the natural tone of your car's engine without introducing any unwanted sound qualities or excessive volume. The Q300 exhaust system utilises specially sized resonators and muffler baffles to maintain power output while still producing a deep and mellow exhaust tone

From start to finish the Invidia Q300 Exhaust Systems are designed with performance in mind with the exhaust route carefully selected to ensure minimal bends, allowing for an unobstructed exit of exhaust gases with minimal restrictions and turbulence. This will allow for improvements in both horsepower and torque, along with improvements in throttle response with a reduction in turbo lag for turbocharged vehicles. Additionally, you get the reward of an aggressive exhaust note.

INVIDIA FRONT PIPE

The factory exhaust will always have restrictions and these restrictions are normally highest near where the catalytic converter is found. Invidia Exhausts use 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.

Because of these reasons, Invidia front pipes and cat pipes make for the most popular exhaust upgrade that adds a substantial bump in both horsepower and torque.

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.
