Porsche 992 GT3 / GT3 RS – EPA-Compliant 400 Cell Catted Downpipes

Engineered for the 4.0L Naturally Aspirated Flat-Six • High-Flow • Compliant •

Introducing Our NEW 400 Cell EPA-Compliant Downpipes for 992 GT3

The Porsche 992 GT3 and GT3 RS are motorsport-derived machines built around a 9,000 RPM naturally aspirated flat-six. While the factory catalysts prioritize restriction and sound control, our NEW EPA-compliant 400 cell high-flow catted downpipes are engineered to reduce exhaust backpressure, improve high-RPM breathing, and enhance the engine’s unmistakable motorsport character — all while maintaining emissions compliance standards.

This upgrade preserves the integrity of the GT3 platform while allowing the engine to operate with greater efficiency and clarity at redline.

Why Upgrade to 400 Cell?

  • EPA-Compliant 400 Cell High-Flow Catalysts: Increased exhaust efficiency while maintaining compliance standards.
  • Improved High-RPM Flow: Reduced restriction enhances top-end breathing and throttle precision.
  • Enhanced Motorsport Character: Sharper, more defined exhaust note at elevated RPM.
  • Track-Focused Performance: Optimized for spirited driving and circuit use without sacrificing reliability.

Engineering & Performance

  • Optimized Flow Architecture: Designed to minimize backpressure while preserving catalyst efficiency.
  • Mandrel-Bent Tubing: Smooth internal transitions for consistent exhaust velocity.
  • Precision TIG Welding: Built to withstand extreme exhaust temperatures during sustained high-RPM operation.
  • Direct OEM Bolt-On Installation: Utilizes factory mounting locations for seamless fitment.
  • Engineered to Pair with Valvetronic Exhaust Systems

Sound Character

  • Stock Exhaust + Downpipes: Noticeable increase in clarity and presence with improved high-frequency resonance.
  • Valvetronic Exhaust + Downpipes: Maximum transformation — sharper transitions, heightened induction character, and a more race-inspired signature.

Construction & Durability

  • Premium high-grade stainless steel construction
  • High-temperature resistant 400 cell catalyst cores
  • OEM-style sensor placement for proper operation
  • Engineered for long-term reliability under sustained high-RPM conditions

Allow your 992 GT3 to breathe as it was engineered to — precision performance, starting at the source.

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.
