cp-e 3" Stainless Steel High-Flow Catted QKspl Downpipe for all 2015, 2016, 2017, 2018, 2019 and 2020 EcoBoost Mustangs.

Create some significant gains on your 2015-2020 EcoBoost Mustang with this 3" Stainless Steel High-Flow Catted QKspl Downpipe (P/N: FDDP00006T) from cp-e. This EcoBoost Mustang downpipe replaces the choked factory pipe and its restrictive cat, resulting in reduced backpressure, decreased turbo spool time and improved performance!

Features and Benefits:
- Mount to Stock or 3" Exhaust Flanges with no Exhaust Leaks
- Laser-cut Stainless Steel Bracket and Turbo Flange
- Industry-leading Stainless Steel Flex Joint
- Full 3" Mandrel Bent 304 Stainless Steel
- Extra O2 Bung for Adding a Wideband Sensor
- Metallic Honeycomb High-Flow Catalytic Converter
- Satin Titan Finish for Added Strength
- Made in the USA

Please Note: Even though this downpipe includes a high-flow catalytic converter, a custom tune/calibration will be required after installation (NOT included).

This downpipe uses your EcoBoost Mustangs stock downpipe support mount. cp-e welds a laser-cut stainless steel bracket onto each downpipe and even supplies a laser-cut gasket adapter with the downpipe. This adapter allows you to install the downpipe to a stock exhaust without the worry of exhaust leaks. Without this adapter, the 3" downpipe would be larger than the stock exhaust flange, allowing exhaust gasses to escape past the gasket. This downpipe also features a beautiful satin finish that strengthens the stainless steel and welds for added reliability.

cp-e designed this downpipe to match with the stock turbo. It is manufactured in the USA from premium quality American-made "bright annealed" 304 stainless steel and is mandrel bent throughout for less turbulent exhaust flow. This downpipe includes three O2 bungs to accommodate the two stock O2 sensors and to give you the ability to easily add a wideband sensor. It also comes with a metallic honeycomb high-flow catalytic converter to help with performance.
