Stainless Steel High Flow Downpipes - Alfa Romeo Stelvio Quadrifoglio (QV) MY2017+

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)
