Porsche 991 GT3 / GT3 RS – Valved Sport Exhaust System

F1-Inspired • RSR Sound • 9000 RPM Symphony

Overview

This system is truly unparalleled in sound quality. After over a year and a half of dedicated research and development, we’ve engineered an exhaust experience that must be heard to be believed.

When Porsche introduced the DFI engine in the 991 GT3, many feared it would lack the soul of the legendary Mezger. But with a screaming 9,000 RPM flat-six, Porsche delivered in spades. Still, the factory setup leaves much to be desired when it comes to rawness and that elusive F1-style sound.

At Valvetronic Designs, we’ve crafted a system that elevates your GT3 experience. Featuring 2.5-inch piping, a large stamped cross-section X-pipe, and added loop sections to lengthen the exhaust path, this setup achieves the high-pitch motorsport tone enthusiasts crave. Combine it with our free-flow headers, and your 991 becomes one of the most exhilarating sounding machines on the road.

Sound Dynamics

This exhaust is designed to emulate the Porsche RSR race car:

  • Valves Open: An uncompromising sound experience with aggressive flames on upshifts and a crescendo that builds all the way to the 9000 RPM redline. Pure F1-inspired drama.

  • Valves Closed: Volume is tamed for comfort on long motorway drives or early-morning starts. Cabin drone is eliminated, keeping the experience refined even with valves shut.

Features

  • Full 2.5-inch system from front to back

  • Large stamped cross-section X-pipe for F1 tone

  • Added loop sections for enhanced sound pitch

  • Optional free-flow headers for maximum performance and sound quality

  • Vacuum-actuated exhaust valves with factory-like operation

  • Precision TIG welds for high strength and durability

Fitment

  • 2014–2019 Porsche 991 GT3

  • 2016–2019 Porsche 991 GT3 RS

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.
