Fabspeed Porsche 991 Carrera Valved Exhaust System

Fabspeed’s complete Valved Exhaust for the 991 Carrera combines Maxflo performance side mufflers (with Deluxe quad-style tips) and a valved center-muffler-bypass X-pipe. The result: a deeper, throatier flat-six note with genuinely large midrange gains — and with the valves open, a bold roar the stock car simply can’t make.

Power & weight

Dyno results show gains of up to +23.5 whp and +31.6 lb-ft at 3,900 RPM (+10.9 whp / +14.5 lb-ft at peak), while saving 13 lbs versus the factory components.

Features

• Fits all Porsche 991 Carrera vehicles (2012–2016)
• Includes: Maxflo side mufflers, valved center bypass X-pipe, and valve controller kit (with the standard, non-PSE option)
• 14–16 gauge CNC mandrel-bent T304L stainless steel
• Direct bolt-on replacements for the factory parts; no Check Engine Light; complies with most emissions regulations
• Deluxe quad-style tips in your choice of finish
• Fabspeed Lifetime Warranty

Fitment notes: 2012 was a split model year — verify whether your car is a 997.2 or a 991 before ordering. If your center console has the exhaust-tip (PSE) button, select the PSE option at checkout.
