Product Highlights:

PPE’s Manifold and Up-Pipes are designed to maximize power and flow characteristics.

The entire Manifold and Up-Pipe exhaust system is designed to lower exhaust gas temperatures, reduce drive pressure, and accelerate turbo spool-up while maintaining reliability. Designed for closed course racing vehicles not to be used on the street.
