Capristo Delete Pipes To Suit BMW M3/M4 - 02BM07403008

<p>This Package Includes:</p>

<ul>
<li>BMW M3/M4&nbsp;Racing Test Pipes (Downpipes) 02BM07403008&nbsp;</li>
</ul>

<p>&nbsp;Using test pipes removes the flow restriction a catalytic converter places on an exhaust system, while increasing the horsepower.</p>

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

<p>Lambda or Oxygen Sensor Bungs are pre-installed and threaded.</p>

<p>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.</p>

<p>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).</p>
