How it Installation?

Step 1:

Remove the two original bolts on the ball flange at the downpipe outlet, and loosen the clamps connecting the upper and lower sections of the stock downpipe. Remove the nut securing the support plate to the engine. Keep this nut; it will be needed later.

Step 2:

Use a pry bar to move the particulate filter backward so that the lower end of the stock downpipe can drop down and be removed. Loosen the original V-clamp at the turbocharger outlet. Once loosened, the T-bolt can be removed from the clamp.Remove the bolt securing the bottom bracket of the upper downpipe. Do not discard this bolt. The upper section of the downpipe can now be removed.

Step 3:

First, install the upper pipe onto the turbocharger. It is recommended to over-expand the original V-clamp beforehand, then place it onto the turbocharger outlet flange, adjusting its orientation so that the nuts and bolts can reach it.

Step 4:

Place the upper pipe in position, aligning the holes on the support bracket with the bolt holes on the engine. Loosely tighten the original flange bolts. Rotate the upper pipe into position, ensuring it is flush against the turbocharger outlet. Move the V-clamp onto the flange and tighten the flange bolts on the support bracket to secure the pipe.

Step 5:

Re-fasten the T-bolts on the V-clamp and begin tightening it. Before fully tightening the clamp, loosen the flange bolts on the support bracket to ensure the upper pipe flange properly aligns with the turbocharger flange. Continue tightening the V-clamp, but before fully tightening, retighten the flange bolts to ensure the support bracket is completely secured to the mounting surface. Now, fully tighten the V-clamp.

Step 6:

Place the provided clamps onto the lower exhaust pipe, then slide the lower exhaust pipe onto the upper exhaust pipe, ensuring the support plate holes align with the mounting studs. Install the flange nuts onto the mounting studs to secure the support plate, then tighten the clamps. Using the previously removed original bolts, secure the double-bolted downpipe flange to the original exhaust flange.

DESCRIPTION

Product Overview

  • Many truck owners install a cold air intake, flash a tune, and swap the DPF delete pipe, yet wonder why the turbo still feels choked.
  • The factory 15-19 downpipe features a brutal, flattened section to clear the bellhousing that pinches your exhaust flow down to a pathetic 2.5 inches.
  • It permanently cures the notorious factory heat shield rattle, prevents flex pipe cracks under high boost, and serves as the absolute foundation for any high-performance 6.7L build.

Key Features

  • Heavy-Duty T409 SS Shell: Built from heavy-gauge T409 stainless steel to defend against severe thermal shock, high-EGT stress, and corrosive winter road salt.
  • Smash the 2.5" Bottleneck: Replace the heavily pinched factory pipe. The uniform 4" diameter provides unhindered exhaust velocity directly from the turbine wheel outlet.
  • Reinforced Flex Protection: Upgrade the weakest link. The high-performance flex section withstands the intense exhaust temperatures and increased vibrations of tuned trucks without split or leak risks.
  • Instant VGT Turbo Spool: Erase low-end turbo lag completely. Near-zero turbo backpressure allows the compressor to spool up faster, which delivers a sharp, immediate throttle response.

FAQ

Q: I already have a 4" DPF delete pipe installed. Do I really need to replace my stock downpipe?

A: Yes, if you want full performance. factory 15-19 downpipe is pinched down to 2.5 inches to clear the transmission. This means exhaust still chokes right at the turbo exit. Upgrade this 4" Downpipe removes this ultimate restriction and allows engine to breathe in a uniform 4" path from start to finish.

Q: Which mid-pipe or full exhaust setup should I buy to pair with this 2015-2019 Downpipe?

A: To maximize your airflow and build a complete high-flow system, we highly recommend you pair this downpipe with 4" DPF Delete pipe or 4"/5" Full Exhaust.

Q: Will this 4" downpipe fit a 11-14 or a 20+ Ford 6.7L Powerstroke?

A: No, it will not. The 11-14 trucks utilize a different factory turbocharger setup and the 20+ trucks have entirely different engine bay clearances. If you drive a 20-24 model, please purchase 4" Downpipe.

Q: Why should this downpipe be the first thing I upgrade on my 15-19 truck?

A: Beyond the 2.5" airflow restriction, the stock downpipe welded heat shields crack and rattle at idle, and the factory flex pipe splits open under high-boost tunes. This 4" upgrade fixes all three issues at once.
