Smiley Autowerks

Do you have a turbocharged Porsche and wish it had the naturally aspirated sound of the GT3/GT3RS? Look no further!

We are excited to introduce the first pair of our production 991.2 GT2RS Exhaust Systems utilizing the z pipe, crafted here at Smiley Autowerks . This exhaust system delivers the authentic Porsche sound that these cars should have had from the factory. It allows the turbos to whistle while enabling both banks of exhaust to properly cross over and resonate. The result is a higher-pitched, cleaner sound with reduced drone, along with improved exhaust scavenging. Say goodbye to your track weapon sounding like a dump truck!

Our exhaust systems are available for immediate order:
- Catted and Race Versions
- Stainless Steel and Inconel Options
- Worldwide Shipping

Upcoming Systems:
- 992.1 GT3/GT3RS/ST - Coming Soon
- 992.1 Turbo/Turbo S - Coming Soon
- 991.1/991.2 GT3/GT3RS - Coming Soon

Please note that the Z-pipe design is patent pending.

A huge thank you to and .jon for allowing us to develop this new product on their cars!
