The CTS Turbo de-cat downpipe for BMW N55 with pneumatic wastegate is designed for optimal exhaust gas flow and greater performance potential. It replaces the factory downpipe with a less restrictive design and provides a sportier exhaust sound.
The product was designed using modern CAD technology, allowing it to fit directly in place of the factory downpipe. It is made from T304 stainless steel, manually TIG-welded and back-purged to protect the inside against oxidation, ensuring long-lasting reliable operation.
Product details:
- Precisely designed and tested on a vehicle in real-world conditions
- T304 stainless steel construction, TIG-welded and internally protected against oxidation
- Replaces the restrictive factory downpipe
- Effective performance upgrade
