BMW M3/M4 - Racing Test Pipes (Downpipes) 02BM07403008

Capristo Automotive


This Package Includes – BMW M3/M4 Racing Test Pipes (Downpipes) 02BM07403008 

 Using test pipes removes the flow restriction a catalytic converter places on an exhaust system, while increasing the horsepower.

The silencing effect of the converters is also removed, enhancing the aggressive engine sound. Test pipes are ideal for track days and race applications.

Lambda or Oxygen Sensor Bungs are pre-installed and threaded.

The iconic CAPRISTO Valved Exhaust System offers the best of both worlds through its capability to produce an aggressive exhaust note under acceleration and a more subdued sound for city driving.

 CAPRISTO Exhaust systems are engineered and manufactured utilizing advanced 3D Laser-Scanning, CAD Design, Digital prototyping, and CNC-bending/milling at our factory in Germany. Each system is made of high-grade T309 (1.4828) Stainless Steel and hand-polished to a mirror finish. After extensive research, this specific alloy was chosen for its sonic resonance properties, low weight, and durability, which are close to the properties of Inconel (used in F1).


*The exhaust system is designed to be installed directly into existing OEM mounting points without additional modifications. 


*Recommended For Off-Road and Track Use Only*
