The Porsche 981 platform which replaced the 987 Boxster and Cayman still features a DFI 2.7L or 3.4L engine. However there are big performance gains to be had in the exhaust system. A normally aspirated engine does not want to lose alot of backpressure as this will affect low end torque. With the right combination of exhaust flow and backpressure, getting more horsepower and torque can be easily obtained. Not only that, your sports car will actually sound like it should!

The all stainless steel headers feature precision TIG welding with a beautiful merge collector. The headers feature high flow catalytic converters. Because of the increased exhaust flow, these headers can trigger a check engine light. We recommend aftermarket ECU tuning to get rid of this CEL if it appears.

With the addition of our Agency Power performance muffler, the Porsche 981 Boxster S gained 11whp and 24ft/lbs of torque. These fit all S and Non S Porsche Boxster and Cayman 981 from 2013 and on. All Agency Power parts come with a limited lifetime warranty when you fill out the form here.

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.
