Why 3" Inch piping diameter? After much research, calculations, testing, and development we found that based on the 4.0T engine's demands, 3" piping diameter is the largest piping diameter that can fit in order to optimize the vehicles performance. With smaller than 3" exhaust you end up choking off the 4.0T's Turbos not allowing enough exhaust flow.
• 3inch In-house Mandrel Bent System for Optimal Flow and Performance
• Non-Restricted High-Flow Exhaust System for Optimal Power Gains
• American T304 (.065) Stainless Steel for Optimal Durability and Longevity
• High-Quality 304 Stainless Steel Clamps
• High-Flow Rear Muffler Design
• In House Mandrel Bent Piping
• Quad 3.5" USA Made Stainless Steel Hand-Polished Exhaust Tips
• 100% USA MADE
You can expect an increase in turbo performance with less turbo-lag and more top-end power. Increases may vary depending on downpipe configuration and supporting hardware. We recommend our JHM 3" 4.0T Downpipes to be paired with our system to optimize exhaust flow and performance gains.
