Porsche 911 Carrera / S / GTS (991.1) – Valved Exhaust System

Rich F1 Sound • Lightweight Construction • OEM-Style Valve Control


Overview

Welcome to the Valvetronic Designs Catback Exhaust System for the Porsche 991 platform. Engineered from the ground up, this system is built to deliver a truly rich F1-inspired sound while maintaining comfort and refinement when cruising with the valves closed. Featuring a large center X-pipe, the system creates a smooth exhaust flow, balancing aggression with sophistication for the perfect 991 soundtrack.


Sound Dynamics

  • Valves Open – Exhaust gases flow with minimal restriction, unleashing a sharp, high-pitched F1-style sound that transforms your Porsche into a motorsport machine.

  • Valves Closed – Sound is tamed significantly, reducing unwanted cabin frequencies and creating a calm, refined experience for daily driving.

  • The system strikes the perfect balance between raw emotion and everyday usability, offering maximum enjoyment without compromise.

  • Available in Anodized Gold T304 Stainless Steel or Blue Burnt Titanium

  • Vacuum-actuated exhaust valves with controller for OEM-like operation

  • Standalone valve control option for vehicles without factory valves

  • 21.8 lbs lighter than the factory exhaust (T304 Stainless version)

  • Precision TIG welds for strength and durability

  • 100% reversible – always able to return to stock configuration


Fitment

  • 2012 – 2016 Porsche Carrera / Carrera S / Carrera GTS

  • 2014 – 2016 Porsche Targa 4 / Targa 4S / Targa 4 GTS

Porsche 911 carrera

"Exhaust was awesome its what the car needed didn't believe it would wake up the car that much with just the Exhaust but it did i love it"

gabe p. (5/5)

Hands down the best craftsmanship,

"Hands down the best craftsmanship, looks and Sound of any similar product out there!"

sam y. (5/5)

Amazing!

"Purchased this for my 991. 1 Targa and as soon as I put my foot down, the valves open and the engine screams get out of my way, a massive smile immediately spreads from ear to ear. Workmanship is amazing, sounds amazing and I LOVE it. Only issue ove notes is the install was a little tricky and I still can’t get the back pipes evenly level. The package did arrive in rather rough shape so I’m wondering if it’s not slightly bent somewhere?"

Q&A

Does this fit a base 911 with 3.4 liter engine without PSE?
Yes, this exhaust system will fit your base 991.1 Carrera with the 3.4L (2012–2016 models) even without Porsche Sport Exhaust (PSE). It's a direct bolt-on cat-back designed for the entire 991.1 Carrera lineup (base, S, GTS), and non-PSE cars have factory exhaust valves that the system integrates with via an optional controller for manual operation. No modifications needed.
