Here is the Supersprint performance exhaust for the 2020 Alfa Romeo Stelvio Quadrifoglio 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.
