Alfa Romeo Stelvio Quadrifoglio Downpipe Upgrade!

Ideal downpipes are American made and hand crafted using high quality stainless steel. With meticulous finish work and TIG welds, they feature CNC machined (corrosion resistant) 304 Stainless Steel v-band flanges that mate and index precisely into the factory turbine discharge housing. The tubes are CNC bent, high quality 3” diameter tubing.

The downpipes have excellent placement within the vehicle, due to our 3D scanning of the OEM downpipes and CAD models to optimize flow path and fitment.

Our downpipes have the lightest weight on the market and come in 2 different configurations:


Catless RACE ONLY downpipes with an OEM exhaust connection.

Catless RACE ONLY Downpipes with a 3” outlet (requires fabrication to create a FULL 3” exhaust system)


 If you find you need replacement gaskets while removing your OE downpipe we have replacements available HERE 

Fits all 2017+ Stelvio QV models

All Stelvio QV downpipes are made to order, please allow up to one business week build time and two weeks for catted variants.
