The culprit? The factory 20+ downpipe features a heavily crimped, flat section to clear the crossmember, which pinches the exhaust flow down to 3 inches or less.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThis premium 4\" SS Downpipe replaces that pinched factory restriction with a uniform, mandrel-bent 4-inch structure straight from the turbo exhaust housing.\u003c\/li\u003e\n\u003cli\u003eIt eliminates the #1 remaining restriction in your exhaust path, unleashes instantaneous VGT turbo response, and drives down hazardous exhaust heat.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003e\u003cspan data-type=\"text\"\u003e\u003cspan data-type=\"leaf\"\u003eKey Features\u003c\/span\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHeavy-Duty T409 SS Build: Engineered from rugged T409 stainless steel to withstand intense thermal shocks, underhood heat cycles, and harsh road salt.\u003c\/li\u003e\n\u003cli\u003eEliminate Crimped Bottleneck: Replace the flattened factory pipe.

Why do I need to upgrade to this 4\" Downpipe?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Because factory downpipe is the new bottleneck. To clear the frame, Ford flattened a section of the stock pipe down to under 3 inches. Even with the DPF gone, exhaust still chokes at this narrow pinch point. Upgrading to this 4\" Downpipe creates a true, uniform 4\" path for maximum efficiency.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I install this 4\" downpipe if I want to keep my factory DPF emissions system intact?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes, you can. If factory downpipe is rusted or cracked, this serves as a heavy-duty, high-flow replacement that bolts directly into the stock emissions canister. No delete tuner is required if you retain the factory DPF setup.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will this 4\" downpipe trigger a Check Engine Light (CEL) on my dash?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: If connect it to a stock factory DPF system, it will not throw codes. However, if you use it to run a full DPF delete setup, you must flash truck with a proper delete tuner like our Mini \u003cspan style=\"text-decoration: underline;\"\u003e\u003cspan style=\"color: rgb(43, 0, 255); text-decoration: underline;\"\u003e\u003ca href=\"https:\/\/www..com\/products\/-2017-2019-6-7l-ford-powerstroke-mini-maxx-tuner-v2-dpf-def-egr-delete-tuner\" title=\"Mini Maxx Tuner-V2\" style=\"color: rgb(43, 0, 255); text-decoration: underline;\"\u003eMaxx Tuner V2\u003c\/a\u003e\u003c\/span\u003e\u003c\/span\u003e to disable the emission sensors permanently.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Which delete pipe should I buy to pair with this 4\" Downpipe for a complete turbo-back system?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: This downpipe connects perfectly to any DP-Back Exhaust pipe.
