Exhaust bolt repair kit for Porsche DFI Engines on 911/997/991/ Boxster & Cayman (9A1) 2009-Onwards
Holy broken bolts Batman! Even the latest generation of DFI (9A1) heads on the water-cooled engines are reporting broken exhaust bolts. 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 SR069, 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 SR069 plate is locked in place (by threading a Thumb Screw over a broken bolt or by using a supplied bolt threaded through the SR069 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. Also includes our SR065D drill guide.

Information
Exhaust manifold to head gasket
This OE Match exhaust manifold to cylinder head gasket is a replacement exhaust sealing gasket for Porsche GT4 RS, 991 GT3 / GT3 RS, and 992 GT3 / GT3 RS models. It is designed to match the original-style fitment and function, helping provide a secure seal between the exhaust manifold and cylinder head.
Sold individually, 2 required per vehicle
Fits:
Porsche 991.1 GT3 / RS
Porsche 991.2 GT3 / RS / R / Speedster
Porsche 992 GT3 / RS
Porsche 718 GT4 RS Cayman
Diagram ref no 3
The exhaust manifold gasket seals the joint between the cylinder head exhaust ports and the exhaust manifold. It helps prevent exhaust gas leaks, maintains correct exhaust flow, and supports proper engine performance, emissions control, and exhaust system operation.
Functions
• Seals the exhaust manifold to cylinder head joint
• Helps prevent exhaust gas leaks
• Supports correct exhaust flow from the engine
• Helps maintain engine performance and response
• Reduces the risk of ticking noises caused by manifold leaks
• Replaces compressed, leaking, damaged, or worn original gaskets
• OE Match replacement for exhaust system service and repair.
Why Replace This Part?
Exhaust manifold gaskets are exposed to extreme heat, pressure, vibration, and repeated heat cycling. Over time, the gasket can compress, burn through, crack, or lose sealing ability. A failed gasket may cause exhaust ticking, fumes, loss of performance, incorrect emissions readings, or heat damage around the manifold area. Replacing the gasket helps restore a reliable exhaust seal and correct system operation.
When to Replace This Part
• The exhaust manifold has been removed
• Exhaust gas leakage is present at the cylinder head joint
• A ticking or blowing noise is heard from the manifold area
• The gasket is crushed, burnt, cracked, or damaged
• Exhaust fumes or soot marks are visible around the manifold flange
• The exhaust system or headers are being serviced or replaced
• The engine is undergoing repair, rebuild, or preventative maintenance.
Where it fits on the car
This gasket fits between the exhaust manifold and the cylinder head. It is used at the exhaust port sealing face and should be installed according to the factory exhaust manifold layout and tightening procedure.
