This is the Invidia Q300 Cat-Back Exhaust System. The Q300 is a highly coveted exhaust system among enthusiasts because it gives them everything they want in terms of a performance upgrade. You get premium fabrication using quality materials that are combined with machined welds. The design features very smooth radius bends with an increase in piping diameter to allow for an unobstructed flow path for the exhaust to escape. And the beautiful polished finish right out of the box will check all the aesthetic boxes to provide the rear of your vehicle with a pronounced look. The final result will provide the user with a nice increase in power and torque, and improvements in the throttle response. The most rewarding aspect is the race-inspired sound. From mild bolt-ons to full builds, the Invidia Q300 will change the character of your vehicle to make your driving experience much more enjoyable.
