Lightweight Competition Exhaust System
A lightweight competition exhaust for the Porsche 981 Cayman GT4 and Boxster Spyder (2015-2016), a stripped-down version of Fabspeed's Valvetronic Exhaust built for maximum sound, minimum weight and maximum power. Expect a genuinely loud flat-six roar with abundant burbles and backfires; pair it with Fabspeed's turndown tips if track sound limits are a concern. Paired with Fabspeed's Race Headers it's been shown to push 375 whp (450 hp at the crank), or 371 whp with sport headers, while eliminating the factory torque dip around 3500 rpm. It's cat-back, bolting straight onto the OEM catalytic converters, uses 2.5-inch straight-through piping, and weighs 19 lb less than the factory rear muffler system. Built from 14-16 gauge T304L stainless steel, in matte carbon fiber or single-wall brushed stainless tips.

Is this exhaust street legal?
Yes, it's cat-back and bolts onto the OEM catalytic converters, unlike a full competition system.
Is there an option for quieter track running?
Yes, Fabspeed recommends pairing it with their turndown tips if sound limits at the track are a concern.
Which option should I choose?
Add the Porsche Slip-On Turndown Tips if you're running this at events with strict sound limits; Fabspeed designed them specifically to help pass track noise checks with this exhaust. Skip them for the loudest, most open exhaust note. The Carbon Fiber and Single Wall Brushed Stainless Steel tip choices are a finish decision only, with no functional difference.
