Fiesta Ecoboost cat back onto an ST

[Nathana94]

Find myself asking for help more than I’ve been able to help on here haha

i put a cobra sport cat back on my fiesta ecoboost 1.0 and it sounded so good. I’ve recently part exd it for an ST, but kept the cobra exhaust. Would this fit onto the ST?

i get anything can be made to fit with the right sleeves or cuts, but I’m wondering if it will just... fit?

cheers!

yeah should do if it was intended for an ST in the first place it should just bolt on.

It was intended for the 1.0 - would I be bad on performance if I was to try and get it on? Not even sure it will go on, I just assumed with it still being a fiesta it may fit

the mounting points for the hangers should be in the same spot, what diameter is the cobra pipe, as the standard 1.0 pipe is different to the standard ST pipes. ST stock size is 2.5 inches (63.5mm) sop if the cobra system is this then it should fit, would also depend if the gasket part where it bolts onto the car if the holes line up and fit.

side note if it doesn't fit and are low on cash to get another system, you could get a exhaust shop to modify it to fit properly.
