The DS-1 is a precision engineered hi-flow race catted 5” mandrel bent stainless steel downpipe for the 2016+ BMW 340i. It is 3D computer designed to minimize bends and maximize flow while maintaining factory-like fitment.
- Faster turbo spool up, increased/much-deeper exhaust note, much improved throttle response
- Ultra-high flow 200 CPSI race catalytic converter
- True 5" (127mm) diameter catalyst for 56% less flow restriction and better emissions than 4" sports catalysts used by competitors
- T304 high grade stainless steel
- TIG welded with chemical weld passivation for enhanced appearance and corrosion protection
- 3D computer design and flow simulation with minimized bends and gradual transitions for smooth airflow
- OEM-like fitment with factory O2 sensor functionality
- CNC flanges and precision laser-cut brackets
***We have thousands of miles on this catalytic converter with no CEL. We have monitored and data logged the emissions numbers and compared the numbers to the factory downpipe with great results.****
Product Applications:
CG Precision has meticulously designed the DS-1 downpipe to improve on the 340i's sound, throttle response, horsepower and torque. CG designs, engineered, machines, and fabricates all exhaust products in Tucson AZ, USA.
