Porsche Cayman GT4 Celebrates Its 911 Engine with Custom Race Headers: Crazy Sound

When you’re inside Cayman GT4, the sheer idea that you drive a car that finally managed to convince Porsche engineers to put that 3.8-liter in the middle, not at the back, is enough to make you smile.

Nevertheless, some owners will want their Cayman GT4 to be more special than others, and this is where the tuning world steps in. Pennsylvania-based Fabspeed Motorsport has just released a custom header offensive for the track-special version of the mid-engined Porsche coupe.

The tuner offers both Sport headers, and Race headers. And while the main aim here is to optimise the exhaust flow, the resulting aural treats make for one memorable mid-engined Zuffenhausen machine.

Time to talk about the performance gains brought by these exhaust goodies

Depending on the model chosen, the flat-six can gain 18 hp and 15 lb-ft (that's 20 Nm for all you reading this across the pond) in Sport guise, while the Race version brings an output premium of 27 hp and 38 lb-ft (51.5 Nm).

It’s not like the standard 385 hp of the 3.8-liter heart are not enough, but these guys are always happy to take your GT4 higher.

Nevertheless, we’d be extra careful with the idea of modifying such a car. Porsche’s GT division will only roll out about 2,500 units of the extreme Cayman per year. This means we are dealing with a future collectible here and installing aftermarket parts is not exactly something you want to do when embarking on this type of adventure.

We’ll remind you the Cayman GT4 also rides on a suspension borrowed from the 911 GT3. Perhaps later on in the vehicle’s life we’ll get to see bespoke suspension works following this path. Until then, you can check out the two Fabspeed Motorsport header versions in the clips below.
