Overview

Our Megaphone crack pipe features...

  • Inconel 625
  • Megaphones for enhanced wave strength (more power)
  • Full 3.5" X Pipe merge

 

YOU HAVE BEEN WARNED! This system sounds badass, BUT….

  • It was designed for race cars, and as such, it is UNCOMPROMISING
  • It drones at certain RPM
  • It vibrates the whole car
  • It causes anything that is loose to rattle and buzz

 

If anything above is concerning to you, the Crack Pipe is NOT for you!

 

For 997's with Dundon V2 Street Headers, only Mini Crack Pipe is available,*

    Great quality, fit and finish is fantastic, instructions were very thorough. Installed on 991.2 GT3 Cup, raced it the next day and everything held up wonderfully!
