I will see that install and raise you a set of bassani equal lengths on a gen2 lightning sir!
The header on the focus wasnt too bad. Getting everything out was the hardest part. bolt your flexpipe to the header before you reinstall it....even if you leave it loose. its pretty straight forward. If dont get a tune, yuo will probably throw a code. There are some cheater tricks that sometimes work to not throw a code without a tune.
