There are not a lot of bad things to say about the 997 Turbo. It’s powerful, fast, and comes with a long list of standard options. But if there were one thing we could find to complain about, it would be the Turbo’s relatively anemic exhaust note. The Tubi Style street exhaust system for the 997 Turbo is a major improvement over the factory part both in terms of sound and performance. By using 200 cell high-flow catalytic converters and a proprietary free-flowing center muffler, the Tubi system relieves backpressure and allows the VTG turbochargers to spool much quicker and react more responsively to driver input. As a result of this free flow of exhaust gasses, the Tubi system is responsible for 15-20 horsepower gains, and also produces a much more pleasing exhaust note. This system is very commonly referred to as “the best of both worlds” because of its unique ability to combine performance and drivability. During normal driving and highway cruising the sound is very similar to stock, without any increase in cabin resonance. During hard acceleration the free flowing characteristics take over and create a much sportier sound.
Fits 2007-2009 911 Turbo models.
