2016 Fiesta Zetec S diffuser swap

[Danny|92]

Just a quick question, I'm pretty sure this is do-able, however I just want to confirm before ordering.

As the title states I have a 2016 Fiesta Zetec S Red Edition, I love pretty much everything about the car looks wise aside from the rear diffuser, to me it lets the look of the back end down slightly.

What I am thinking of doing is converting to an ST style diffuser, If I buy the 2 parts linked below would they just be a straight swap:

Upper diffuser

Lower diffuser

Thanks for any help!

Yes, drill out the existing rivets then re-rivet or bolt it on. Your exhaust might be poorly positioned though.

Don't forget the 2 nylon nuts in the centre.

The original exhaust will look silly, need extending at the very least.

Cheers guys!

I won't be doing it right away, will likely look into an exhaust as well before I make any move on the diffuser, just wanted to make sure I was right in thinking it was a straight swap.
