Porsche 991.2 GT3 Cup Products

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,*

Add Power and great sound and experience your Porsche’s true capabilities with the Dundon Power Package. Intentionally designed to bring big power with and distinct sound we all love, this kit is perfectly tailored to add more muscle, better sound, and increased performance to your specific GT car.

Hardware Kit to Install a 321SS Lifetime Dundon Muffler on 997 and 991 GT3 Cup cars. The 2.5" version also works for 981 GT4/Clubsport cars retrofitting a GT3 muffler using our adapter kit.

When dialing in a track setup on modern GT Porsches, increasing negative camber is a great way to improve front grip and extend tire life. However, the stock tie rods limit how much camber is possible. Dundon Motorsports' Titanium Extended Length Tie Rod ends offer adjustable rods with extended length threads to allow for a more aggressive track alignment without the risk of too-little threads attaching to the steering rack. 

Titanium rod construction keeps unsprung weight down to improve steering feel and performance. We also use high-quality rod-ends, ARP high-strength bolts and spherical bearings paired with a 2-bolt titanium pinch clamp for easy install and adjustment.

Fits all:

996 GT3/RS

997 GT3/RS

997 GT2/RS

991 GT3/RS

981 GT4

991 GT2RS

982/718 GT4/RS

A pair of Lower Control Arm assemblies for your Porsche 991 GT3 Cup or 981/718 Clubsport with serviceable bearings for easy care and feeding. 

These arms use PTFE Monoballs with hardened stainless races to prevent corrosion. Press fit and retained with a snap ring for easy serviceability and replacement of the bearings when at the end of their service life. Easy to remove and replace on site, at the track, or during an end-of-season refresh, just by removing the retaining ring and pressing out. No Spanner wrench and crossing fingers needed. 

These arms fit all OEM brackets, ducts, clamps, and other accessories just like the OEM arms do. 

The spacers are machined to exacting tolerances to the hardware, within .05mm, for zero excess play and no variance on installation. 

PLEASE CHOOSE +3mm or +15mm Lengths. General recommendation: 991 Cup has +15 front. And 981/718 CS has +3 front and +15 rear.
