Porsche Cayenne Turbo S / GT / GTS – EPA-Compliant 400 Cell Catted Downpipes

Precision Engineered for the 4.0L Twin-Turbo V8 • High-Flow Performance •

Introducing Our NEW 400 Cell EPA-Compliant Downpipes for Cayenne

The Porsche Cayenne Turbo platform is a masterclass in performance engineering. However, factory catalyst restrictions limit the full efficiency and character of its 4.0L twin-turbo V8. Our NEW EPA-compliant 400 cell high-flow catted downpipes are engineered to reduce exhaust restriction, improve turbo response, and refine the exhaust note — all while maintaining emissions compliance standards.

Designed specifically for the Cayenne Turbo S, Turbo GT, and GTS, these downpipes elevate the driving experience while preserving the precision Porsche is known for.

Why 400 Cell?

  • EPA-Compliant 400 Cell High-Flow Catalysts: Increased exhaust efficiency while maintaining compliance standards.
  • Improved Turbo Response: Reduced backpressure sharpens throttle input and mid-range delivery.
  • Refined Yet Aggressive Sound: Deeper tone with enhanced clarity at higher RPM.
  • Maintained Daily Comfort: Performance gains without sacrificing drivability.

Engineering & Performance

  • Optimized Flow Design: Reduces restriction while preserving catalyst efficiency.
  • Mandrel-Bent Tubing: Smooth internal transitions for consistent exhaust velocity.
  • Precision TIG Welding: Built to endure high temperatures and sustained boost pressure.
  • Direct OEM Bolt-On Installation: Utilizes factory mounting locations.
  • Engineered to Pair with Valvetronic Exhaust Systems

Sound Profile

  • Stock Exhaust + Downpipes: Noticeable increase in depth and presence without overwhelming cabin refinement.
  • Valvetronic Exhaust + Downpipes: Sharper response, increased volume, and a more motorsport-inspired character while retaining Porsche composure.

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 high performance conditions

Elevate the performance and sound of your Porsche Cayenne — engineered with precision, 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.
