Milltek S550 2.3 Ecoboost Catback

They have brought a panoply of options for the Mustang owner, both GT V8 and Ecoboost, with dual or quad tip options, (Quad requires Roush rear valance- available separately), a variety of tip finishes and resonated or non-resonated systems (non-resonated systems are louder and are equivalent to the US "competition" systems, where resonated would be a "street" system")

Note the Milltek Mustang 2.3 EcoBoost Resonated Systems ARE Approved and Certified for EC use.

Across both dual and quad outlet systems trims are available in a number of finishes from polished stainless, cerakote black, brushed titanium or the new burnt titanium finish.

Also available are Milltek Downpipes for maximum flow, both with hi flow cat and decat options...
