ALFA ROMEO STELVIO QUADRIFOGLIO "Racing Edition" 2.9i V6 Bi-Turbo (520 Hp) 2020 (with valve)

Here is the Supersprint performance exhaust for the 2020 Alfa Romeo Stelvio Quadrifoglio "Racing Edition" 2.9L V6 Twin Turbo.

This engine has a huge potential for more Hp and Torque, which can only come with free-flowing turbo downpipes.
We use HJS Motorsport 100cpsi high volume catalytics, in order to guarantee the same, lowered resistence as our straight-through, Race downpipes.

This is exactly what the Supersprint full exhaust does; the cat-back section is a complement that's perfectly tuned to the downpipes, guaranteeing a stronger, albeit more refined sound.

As a side effect, the Supersprint state-of-the-art downpipes greatly enhance the well-known pops and bangs at shiftpoints, making our full exhaust really stand out in the crowd.

The flap muffler system offers a subdued, no-droning sound in the lower rpm range, and a wild, race scream at higher rpm, when in the open mode.

Systems for replacement of kat for OBD II car models (with lambda sensors before and after the kat.)

These systems can only be used for racing purpose exclusively, in conjunction with the modifications of the engine management system. If used with a stock “ECU”, malfunctions may occur. All modifications must be carried out by qualified personnel only, under the liability of the car owner and at his expense.

Supersprint guarantee is limited to the quality, workmanship and correctly fitting to the intended car model for all race products.
