This system is built per order. Actual delivery time can be 1-2 weeks.

Add 10 wheel horsepower and 13 lb/ft of torque while reducing weight by 36lbs. 

Fabspeed's supercup turboback exhaust system is the ultimate solution for very aggressive sound and performance.

3"(76mm) mandrel-bent tubing that reduces turbo lag and removes 36lbs(16.4kg) of weight while offering an invigorating increase in turbo sound and boxer engine rumble. 

Increased throttle response and track-worthy sound ensures you feel the Fabspeed difference.

We also offer the supercup turboback without a catalytic converter for those looking for the most aggressive exhaust in terms of power, exhaust volume, and turbo noise.

A check engine light can be expected due to eliminating the catalytic converter. The CEL occurrence can be reduced/eliminated through the use of O2 spacers or upcoming tuning solutions. 

Fabspeed highly recommends an ECU tune for proper vehicle operation and to eliminate any possible engine or hesitation issues. 


With sport mode activated burbles and backfires erupt in abundance on overrun, and downshifts summon a bark that will make all eyes and ears around focus on you.

The factory exhaust mutes the turbochargers, the free-flowing Supercup reveals their presence with a very pleasing increase in spooling sounds, adding more character to your driving experience.

The boxer engine rumble is enhanced and refined in a distinct Porsche tone. This system is aggressive and maximizes power while removing unnecessary weight.


The addition of Fabspeed's Supercup Turboback exhaust system with sport cat added 10 wheel horsepower and 13 lb/ft of torque at 4000 rpm as tested on a Dynojet.

Expect more power and response with our cat bypass option. The Supercup Turboback is a very free flowing system and full potential will be realized with a tune.

Fabspeed looks forward to extracting even more power with their hardware in conjunction with a Fabspeed ECU tune at a later date coming as soon as possible.
