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.

This is a set of manifolds (headers) with catalyst bypass to fit third generation model, known as the 981 (2012-2016) Boxster and Cayman.
After the installation of this product the emission light might come on your dash. To remove it you might need to install the lambda sensor extensions from your existing cat.
This is a high quality, 304 grade stainless steel pair of manifolds with secondary cat bypass (decat). Fitting this part will see a substantial power increase and a little extra noise. Check engine lights may come on once this product is fitted depending on your set-up, typically if this is the only exhaust modification you have made they won't trigger.

Titanium is a highly corrosion-resistant material, which is particularly important in exhaust systems due to the exposure to extreme heat and moisture. The corrosion resistance of titanium bolts ensures longevity and reduces the risk of premature failure, ultimately saving the owner from costly repairs.
