      Unleash Turbo Efficiency and Performance Gains. The Boosted Performance 3.50-Inch Downpipe is a critical upgrade for improving turbo response, reducing EGTs, and increasing exhaust flow.

The 3.5-inch diameter ensures smoother flow from the turbo outlet, helping support higher boost levels and overall power delivery—ideal for performance and towing applications alike.
