991.2 GT3RS Products

Taken from our GT3 Cup exhaust program, this exhaust is the ultimate in performance and sound. BUYER BEWARE! This system has drone and vibration (all things that racecars have) and is NOT for the faint of heart.

If you want it louder than all the rest, this is the one for you!

Contains:

• Dundon Street Headers (with our advanced catalytic converters)
• Inconel Crack Pipe muffler delete
• Hardware Kit

No valves, this thing is LOUD!

We'd been asked by a few to make a Crack Pipe that wasn't as much of a commitment but still true to the original Megaphone Crack Pipe. Meet the Mini Crack, this one works with Dundon valved side muffler deletes or our Street Headers, for both 991 and 997! 992 cars will need our cat-back kit or our full street header package. The only sound better than a Porsche is the sound of a Porsche that’s earned its racing stripes. That’s why we’ve designed the Crack Pipe — the ultimate, unbridled expression of Porsche’s Motorsport DNA (with a little help from Dundon Motorsports). If you want to seriously turn heads at the track when you fly by, this is the one for you. It's still loud but the valves do take a bit of the edge off while cruising.

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

Not for the faint of heart, this is LOUD, screams like an RSR at full throttle. 

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,*

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

Built specifically for 991 GT3RS and GT2RS cars. Add negative camber and increase front track width with our extended front inner lower control arm. Extended studs allow for additional shims to hit your camber targets. Also removes rubber bushings from the steering system for improved feel and decreased deflection.

Wider front track & ideal camber = better handling!

• Machined from billet aluminum
• High-end teflon-coated FK bearings
• Extended length, grade 10.9 studs

1. Increased Negative Camber

Our LCA's are slightly longer, and feature high-grade, extended length studs. This design allows for a taller shim stack to achieve more negative camber than what is available from the factory Porsche part.

2. Improved Handling and Grip

Our LCAs allow your car to have a wider front track width, pair that with an increase in negative camber and you will notice a better "bite" during turn in, improved stability and higher cornering speeds.

3. Precision and "Feel"

Our LCAs feature upgraded bushing, no longer do you have to worry about worn out rubber bushings, we use high-grade Teflon-coated spherical bushings. This removes the "slop" you get from the rubber variants and allows for much more precise steering feedback.

These LCAs also feature adjustable caster pucks so that you can readjust your caster (adjusting the wheel forward/backward within the wheel well) while adjusting camber.

4. Better Tire Wear

Dialing in your camber with our LCAs means more even tire wear. Our parts prevent the outer shoulder of your tire from wearing prematurely and ensures a more even distribution of heat and wear across the tread.

Complete set (of 6) rear "dog bone" control arms for your 991 GT3, GT3RS or 992 GT3. Remove rubber from the rear suspension for better feel, less slop, and more grip!
