Although the official reason that catalytic converters are a requirement on all new cars is to control vehicle emissions, most enthusiasts will tell you that the number one goal of cats is to rob your car of valuable horsepower by severely restricting exhaust flow. On a turbocharged car like the 997.2 Turbo, upgrading the exhaust system is an essential part of any performance package and becomes increasingly important as your horsepower goals get higher and higher. Especially in any application using upgraded Billet VTG Turbochargers, even high-flow catalytic converters create unwanted back-pressure and hinder performance.
The Tubi Style Race exhaust system for the 997.2 Turbo is the perfect solution for anyone looking for that best of both worlds package that provides minimal back-pressure and an intoxicating sound that doesn't overwhelm the cabin with resonance. Tubi perfected this formula by replacing the catalytic converters with bypass pipes leading to a specially designed rear muffler that dramatically reduces back-pressure, without any of the negative side-effects. Unlike many other manufacturers whose "race" exhaust systems are simply the same rear muffler as their street application but without cats, Tubi spent a great deal of time designing a new rear muffler specifically for the race application. Why? Because not only is it important that every Tubi exhaust system perform better then the competition, but it has to sound better too. Simply deleting the cats from a street system results in far too much droning and is just too loud. Tubi's rear muffler keeps the characteristic exhaust note that makes the 997.2 Turbo stand out in a crowd, but turns up the volume a notch or two to a level that's perfect in any driving situation. Oh, and did we mention the intoxicating whistle of turbos spooling up? Why would anyone ever want to overpower that beautiful sound with an unrefined, loud exhaust? We're still trying to figure it out ourselves, so take our word for it, you won't regret taking a Tubi Race system for a test drive! Hand made in Italy just for you, there isn't a better race exhaust system available for the 997.2 Turbo or Turbo S.
