GT3 Exhaust Conversion Kit for Porsche Cayman GT4 981

The Porsche GT4 981 has a quality that many appreciate: its sound!

It can always be improved, but all too often that just means "louder". At Team Lupos we didn't agree with that, so we looked at the question from every angle.

For us, what is missing is a touch of madness, of fury... We came to the conclusion that transplanting a GT3 exhaust was THE right solution for lots of reasons:

• Removable tips that are easy to replace
• Exhaust designed for 500+ and non-restrictive
• Passes noise meter checks
• PSE compatible and type-approved
  
• Available used or as an aftermarket build

Solutions exist on the market, but did not fully convince us, so we started from a blank sheet and corrected numerous points:

• Drone eliminated
• Optimised piping layout
• Work on pressure losses
• Fewer joints and welds
• Optimised position of the PSE valve
  
• Plug'n'play use of the PSE control lines
• Use of locking hardware
• Use of quality gaskets
• Added heat shielding

We are proud of the result: handmade in France, tested in real conditions on track and with a 10-year warranty (valves 2 years).

The kit includes:

• The adapter pipes
• The mounting plate for the exhaust
• The PSE-compatible valves
• The manifold / adapter gaskets
• The hardware
