Porsche Cat-Back Valvetronic Maxflo Exhaust System For Porsche 992 Twin Turbo / Twin Turbo S (2021-2025) Models.

Fabspeed Cat-Back Valvetronic Maxflo Exhaust System for 992 Twin Turbo / Turbo S

Upgrade your 992 Turbo with the ultimate cat-back exhaust solution available. This valved exhaust system seamlessly integrates with the factory Porsche Sport Exhaust (PSE) system, allowing you to switch between quiet highway cruising (PSE off) and an exhilarating Twin Turbo sports car sound (PSE on). Purpose: Provides a versatile exhaust system with significant sound and power enhancements, offering both refined cruising and aggressive performance at the touch of a button.

Sound:

With PSE activated and the valves open, the Cat-Back Valvetronic Maxflo Exhaust transforms your 992's exhaust note into a head-turning experience with a substantial increase in volume. Expect a deep, aggressive tone, pronounced pops on downshifts, and enhanced turbo spooling sounds. With PSE deactivated and the valves closed, the exhaust note becomes tame and completely drone-free, ensuring comfortable in-cabin conversations just like the stock exhaust.

Power:

Featuring our signature cast X-pipe and fully CNC mandrel-bent tubing, this system dramatically improves exhaust flow compared to the factory setup. Dyno testing on our AWD Dynojet has demonstrated consistent power gains across the entire RPM range. Low-end turbo spool is quicker, yielding gains of 19.6 WHP and 32.7 ft/lbs of torque at 3100 RPM. Maximum power gains of 48.7 WHP and 53.7 ft/lbs of torque are achieved at 4800 RPM, equating to an impressive 55 HP increase at the crank.

Features:

• Dyno-proven power gains of 48.7 WHP and 53.7 ft/lbs of torque.
• Saves 9.8 lbs / 4.4 KGs compared to the stock exhaust system.
• Completely retains the functionality of the factory Porsche Sport Exhaust (PSE) system.
• Constructed from CNC mandrel-bent 14-16 gauge T304L stainless steel for optimal flow and durability.
• Laser scanned and CAD designed using an Ametek Handyscan 700 for perfect OEM fitment.
• Simple DIY (Do-It-Yourself) bolt-on installation; no cutting or welding required
