For the true hardcore enthusiast Billy Boat Performance Exhaust developed this 3” down pipe for the Dodge SRT-4 as a bolt on upgrade for their 3” cat back. Hand fabricated from 100% T304 stainless steel, CNC mandrel bent 3” tubing and no catalytic converter you will see better throttle response due to reduced turbo lag and quicker spool up as well as increases in horsepower and torque. As with all B&B products this down pipe is back with their limited LIFETIME warranty. *THESE UNITS ARE DESIGNED FOR OFF-HIGHWAY RACING ONLY AND SHOULD NOT BE USED ON PUBLIC ROADS*
