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.

Features

  • 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)

  • Fully mandrel-bent piping for maximum exhaust flow

  • 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

  • Also fits convertible models

Questions?

WE HAVE ANSWERS

How long til' I get my order?

Small items arrive to you in under 1 week

Larger products like full suspension kits must ship freight and can take 1-3 Weeks

Are Installation Instructions Included?

Instructions are included for most parts that require any sort of knowledge to install.

Here's what to do if your parts come WITHOUT instructions:

1. Some parts are genuinely common sense on how they get installed

2. If you can't figure it out on your own, YOUTUBE IS YOUR FRIEND! Our founder started this company from learning how to build headlights off a YouTube Video

3. If there are no videos on YouTube, or instructions anywhere on Google then please CALL OR EMAIL US and we will guide you through or get you instructions from the manufacturer

4. Doing installs on your own is always fun, but sometimes, it isn't. Always consider having your parts professionally installed

ALWAYS CONSIDER US. We sold you the parts, let us install them at THE LAB in Connecticut. We offer enclosed and open cross country transportation.

Of course you won't want to spend thousands on transportation to install lug nuts or emblems but if you are spending a LOT of money on parts, you may just want to send the car our way

What is your return policy if the part doesn’t fit or isn’t what I expected?

If the part was NOT installed, we accept returns within 14 days of delivery.

If the part WAS installed (or attempted installation), we cannot accept a return.

Do your parts come with a warranty?

All parts come with Manufacturer Warranty! Each manufacturer has different warranties so we suggest reading up on their warranty policy before ordering.

I found a better price somewhere else, can you beat it?

YES! If you come across a competitor with a lower advertised price than us, we will BEAT it by at LEAST 1%. Please contact us with proof of the lower priced product.

Do you give out discounts or sponsorships?

NO! We do not give out discounts or do sponsorships. You can get 5% OFF your first order by signing up for text & email notifications. OR just wait until our BLACK FRIDAY Sale that happens once a year.

See It IRL
