Probably any Porsche owner wants more power & better sound, and Panamera is not an exception!
We designed flow-optimized and perfectly fit downpipes, that utilize OEM split design. You can install secondary cat delete pipes with OEM primary catalytic converters and get more aggressive sound without "check engine" light. Or choose our primaries with High Flow low cell catalytic converters or go with the ultimate full catless setup for maximum performance.

Compatible Vehicles:

• 2019- Porsche Panamera 971 GTS Twin-turbocharged 4.0L V8
• 2016- Porsche Panamera 971 Twin-turbocharged 4.0L V8
• 2017- Porsche Panamera 971 Turbo S E-Hybrid 4.0L V8

Available options:

• HJS Ultra High-Performance catalytic converters. Made in Germany most reputed high flow converters for their outstanding characteristics, quality and durability. We offer selection between 200cpsi Euro 5 HD matrix or 200cpsi Euro 6 HD matrix. It is hard to achieve Euro 6 emission requirements with only 200 cpsi matrix, what requires big core diameter and big precious metals loading. That causes significant price increase for those catalytic converters. But we still have alternative options. >> Read more about HJS cats.
• GESI GEN2 400cpsi 5in core made in Canada catalytic converter rated 1000hp/each. New GEN2 series provides a significant improvement in exhaust flow over stock and offers the latest emissions technology for model year 2017 and newer. EPA Compliant catalytic converters have been third-party lab tested to meet or exceed local emissions standards in North America (excluding California) and will address Check Engine light issues with proper engine setup. Read more about G-Sport by GESI cats.
• Double-layer heatshielding is used to protect surrounding parts, wires, and hoses against radiant heat from the downpipes.
  Integrated thermal insulation reduces surface temperature up to 70%! What makes it an absolute winner, compared to usual thermal wrapping or ceramic coatings.
  It’s very important not just for safety reasons but also affects engine performance by reducing the underhood temperature. We highly recommend this option, especially for catted downpipes.

Main Features:

• significant power gain
• faster spool up and better throttle response
• increasing the life of the turbos 
• reducing under hood temperature
• adds a very nice tone to the exhaust

Our Advantages:

• 100% bolt-on installation
• 100% hand made in Russia
• 100% TIG welded and back purged
• the highest quality 1.6mm wall 304 stainless steel

Notes:

Removing of factory catalytic converters will trigger a сheck engine light. Firmware update recommended to get maximum performance gains.
