Invidia Q300 Turbo Back Exhaust Single Exit - Subaru 08-10 WRX Sedan/Forester XT SH 08-13 (5MT/4AT)

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 CATTED DOWN PIPE

The most restrictive component of the factory exhaust system is the down-pipe which begins right after the turbocharger. Invidia Exhausts use a open bellmouth design to completely open up the exhaust flow path out of the turbocharger. This open bellmouth design combined with a larger pipe diameter and smooth bends allows the turbocharger to exhale exhaust gases with fewer restrictions and turbulence. Because of these reasons, Invidia down-pipes make for the most popular exhaust upgrade that adds a substantial bump in both horsepower and torque with a great reduction in turbo lag.

The bellmouth is made from cast 304 Stainless Steel to withstand the high temperatures seen at the turbocharger, with a laser cut cast steel flange to ensure long lasting leak free reliability. A High-Flow catalytic converted is utilised to control emissions for street driving legalities but with minimal impact to exhaust flow. Designed locally to suit Australian Specification Vehicles, this is a 100% bolt on installation for right-hand drive vehicles with no modifications or changes to the steering knuckle required. Factory O2 sensor locations are also retained to ensure compatibility with factory systems.
