Milltek S550 Mustang 2.3 Ecoboost - Downpipe

For maximum flow from your Ecoboost you need to move the air out of the way of your turbo. That's where a Milltek Downpipe upgrade can help you expand your system over and above just a catback.

Milltek offer a variety of solutions based around their high flow 70mm downpipe, either a high flow cat or decat option and an OEM connector or connector to link it to a Milltek catback for maximum gains.

Downpipe modifications nearly always require a TUNE, so please check out our Steeda "Tunes for Life" package.

NOTE : Decat systems are for off road use only

STEEDA NOTE:
On 2018 + EU Models, the OEM exhaust manifolds include a pre-cat GPF (Gas Particulate Filter) which US cars do NOT have. If you install custom headers you will in effect delete the GPF filters which will throw warning lights in your car's dash and is technically not road legal. Steeda Tunes do NOT support custom tuning to enable GPF delete.
