For those who own the ecoboost Mustangs, they see the downpipe and may notice how restrictive it is. Well, I decided to do away with mine. After a lot of head scratching and bolt stripping, I finally got the custom down pipe installed.
It's a great step in the right direction for making the 4 banger sound a lot more aggressive.
In the photos, it's the restrictive downpipe and the catless installed.
