The Invidia Q300 offers a good balance of price and performance. The Invidia Q300 Exhaust is constructed with high-quality SUS304 stainless steel, CNC-machined flanges, and manufactured with a polished finish. Each system features mandrel-bent stainless steel piping for maximum exhaust flow and reduced back pressure. The Q300 exhausts are engineered to produce strong mid to top-end power gains, as well as an increase in horsepower and torque. The Q300Catback offers a great sound with out too much increase in volume. These are great for those wanting to not be overpowered by exhaust noise and use their cars as commuter or long distance transport.
