Exhaust Nuts / Bolts / Studs

Exhaust bolt repair kit for Boxster / 996 / 997 Carrera & Cayman Gen1 1997- 2009 (Not GT3, GT2 or TT engines)



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 titanium components are resistant to rust and corrosion, which can be a common issue with traditional steel studs and nuts. This corrosion resistance ensures that the studs and nuts maintain their integrity, allowing for easy removal and installation when necessary. They are the perfect upgrade for Porsche enthusiasts who demand the ease of access to vehicle's exhaust system.
