Alfa Stelvio Quadrifoglio - Ragazzon 200-cell sport metal cat + OPF delete L+R

Ragazzon Metallic Catalysts 200 CPSI with OPF Delete – Alfa Romeo Stelvio Quadrifoglio (2.9 Bi-Turbo)
Part number: 50.1157.80

This Ragazzon set replaces the original catalytic converters and gasoline particle filters (OPF) of the Stelvio Quadrifoglio. The 200 CPSI sport catalytic converters and the removal of the GPF make the exhaust flow much freer, resulting in a faster-responding engine, less backpressure, and a richer, fuller sound.

Key features:

• 200 CPSI metallic sport catalytic converters (left and right)

• Integrated GPF delete

• Ø76 mm pipe diameter for maximum flow

• Made of high-quality stainless steel with a perfect fit

• Equipped with connections for the original lambda sensors

• Can be combined with the original or Ragazzon center section (adapter sold separately)

Benefits:

• Faster throttle response and smoother power delivery

• Better flow for tuned vehicles

• Deeper, sportier exhaust sound

• High-quality finish and durability

Installation & important points:

• ECU modification is strongly recommended for error-free operation

• Intended for circuit or track use; check local regulations for road use

H&S Corse advice:
For the best results, combine these catalytic converters with custom ECU software and a matching Ragazzon center section or full exhaust system. This will allow you to get the most out of your Stelvio Quadrifoglio – more powerful, more responsive, and with a sound that suits the car's character.
