With more and more broken exhaust bolts reported on the water-cooled engines, the headache of repairing a broken bolt is becoming epidemic. Tasks ranging from a simple exhaust system update through an engine removal, are consistently plagued by snapped, rusted, and broken exhaust manifold bolts. Rarely can an accurate removal of the broken bolt be performed with the engine in the car, and even after removal, the task is time consuming and if not done carefully can lead to a damaged head or faulty repair. STOMSKI RACING's answer to these problems is the SR067, a kit that easily, accurately, and flexibly allows you to drill out the broken bolts - with the engine still in the car- saving time and headaches. A CNC milled plate indexes precisely off the broken bolts and/or bolt holes. Using our uniquely designed Thumb Screws, the SR067 plate is locked in place (by threading a Thumb Screw over a broken bolt or by using a supplied bolt threaded through the SR067 Thumb Screw). With the included pilot drills and drill guides, the faulty bolt can be drilled out, producing a perfectly perpendicular and centered hole that if necessary can be chased with an included M8x1.25 tap.
Kit includes : anodized aluminum fixture, drill bits, tap with extension, drill jigs/guides, Thumb Screws, and hardware in a sturdy storage case.
Now also includes our SR065D drill guide.

These modular headers are the perfect solution for any street driven 992 GT3. Our RENNKRAFT™ modular design features a quick release V-band connector that allows the owner to easily swap between our German made HJS 200 cell cats and QUICKTRACK™ cat bypass "straight pipes" for track use (patent pending). Rennkraft, translated from German is "race power". These unique headers offer true street and racetrack functionality in an innovative precision engineered package.
SOUND:
Many say sound is a subjective thing, but we like to think we've made the 992 GT3 sound objectively better with these high flowing headers. Equipped with our 200 cell cats, you will get a louder exhaust note with a much more raw sound. Higher frequency tones are more defined, and deceleration burbles are more robust and transparent. With the cat bypass pipes installed, the GT3 turns into a motorsport bred monster. At [art throttle the volume isn't overbearing, but the sound is very aggressive and race bred. With the stock muffler in place, there is no drone what-so-ever, even with the cat bypass option installed.
POWER:
After extensive dyno development we found the optimal header length and diameter. With no tune, compared to a stock car we gained 16 whp and 20 ft/lbs of TQ with the Sport Cats and 19 whp and 26 ft/lbs of TQ with Cat Bypass installed. That's a gain of 19 HP and 23 HP, respectively, at the crank! Peak horsepower also increased from our baseline of 452 whp to 461 whp with our HJS Sport Cats and 468 whp with Cat Bypass Pipes. See our dyno graph above for more details.
FEATURES:
• Fits all Porsche 992 GT3 / GT3 RS 2022+ Models worldwide (This system does delete the GPF, and will cause a check engine light for a monitored GPF system unless a simulator or tune is used)
• Impressive dyno proven power gains of 16 whp and 20 ft/lbs of TQ with the Sport Cats and 19 whp and 26 ft/lbs of TQ with Cat Bypass installed
• Save 6 lbs / 2.7 KGs with Cat Bypass compared to the factory headers
• Modular design that uses a V-band clamp so one can quickly swap between cats and cat bypass
• Constructed from CNC mandrel-bent T304L stainless steel
• Switching to cat-bypass for track events prevents catalytic converter degradation during all out competition racing abuse
• With the RENNKRAFT™ system, you can quickly install our QUICKTRACK™ cat bypass pipes for Racing and all out Race track-only competition events
• F1 style high velocity merge collectors
• Designed from 3D scans of the OEM headers so we can achieve perfect bolt-on fitment
• We use German-made HJS HD tri-metallic 200-cell EURO 6 homologated catalytic converters for the best performance and reliability
• We use the largest catalytic converters that will fit in the factory location for maximum flow
• Optimized for maximum performance with NO catalyst generated check engine light, guaranteed, when Sport Cats are installed
• Built 100% in house at Fabspeed Motorsport USA in Fort Washington, PA
• 25+ years of air-cooled and water-cooled Porsche experience went into our design for these hand-crafted headers
• Simple bolt-on installation, no cutting or welding required
• All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty
Why We Choose HJS Catalytic Converters:
HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light. If you'd like to learn more, watch our video about HJS catalytic converters.
