Akrapovič's Slip-On Line represents the first step in the exhaust system tuning process and the muffler can easily be installed onto the Porsche GT3's original system. Built from hi-grade titanium and finished with two eye-catching double round tailpipes, this entry system makes the GT3 more powerful and lighter, and gives the car that unique Akrapovič sound. Designed to make the car stand out from the crowd and increase its appeal even more, the visual delight of the Akrapovič Slip-On can be further enhanced with the addition of an optional carbon- fibre rear diffuser. Beautifully handcrafted from the finest materials and designed to enrich the exclusive look of the titanium exhaust system, the diffuser is a must-have extra for any discerning owner.

The 997.2 Carrera Center Muffler Bypass X-Pipe makes a great compliment to either the factory side mufflers or to Fabspeed's Maxflo Performance Side Exhaust System. It improves exhaust tone and saves weight by replacing the factory center muffler with a lightweight x-pipe.
POWER:
You'll experience a nice seat of the pants power gain. We saw peak gains of 12 whp and 15 ft-lbs.
SOUND:
Without PSE: A subtle improvement, with a throatier, deeper exhaust note. A perfect first exhaust upgrade for your Carrera. Combine with our Maxflow Performance Side Exhaust System for the perfect level of volume and a refined sports car sound.
With PSE: A great delta between valves closed and open. With valves open and the side mufflers allowed to channel through the free flowing CMBP, the exhaust offers a race like, brilliant exhaust note. Very aggressive, noticeable burbles and crackles. With valves closed, return to a refined, non droning civil level of exhaust tone.
FEATURES:
• Fits all Porsche 997.2 Carrera vehicles (2009-2012) (2012 was a split model year, a 2012 911 Carrera could be either a 997.2 or 991, please verify if your car is a 997.2 or a 991 before purchase)
• Improves horsepower and torque by 12 whp and 15 ft-lbs
• Saves 5 lbs. versus the factory center muffler
• Constructed from high-quality .065" thick C.N.C. mandrel-bent T304L stainless steel for optimum flow and maximum durability
• Direct bolt-on replacement for the factory center muffler
• All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty
