What did you do to your Fiesta ST today ?

[Grsemky]

Also the engine side mount would have a more accurate fuel temperature reading since it would be measuring it inside the engine bay where it gets the hottest

Wiring won't be the issue, finding a logical, easily accessed location for the sensor was what I was trying to find... I'm using this guide to save myself a few hundred dollars lol

Finally got my vehicle registration certificate today in Italy. So in 5 days i'll be the proud owner of a Fiesta ST 1.6 😍😍😍😍.

aaaand i got it home
I have just a few things to sort out, like a very weird noise coming from the rear left wheel and the fact then when i stop the car and wait for a little while, there's a really weird noise coming from the hvac zone. Clutch and motor mounts already sorted out so that's very good

'really weird noise coming from the hvac zone...' welcome to blend door madness - there are hundreds of posts to review and determine your approach. Its actually a gear-driven flap which redirects air - floor, defrost, panel and fails...there are 2 (3?) to deal with. Underdash, blind, fingertip access only.

@Bull Run are you using some fancy HS/MS obd reader?

It's a Mishimoto with black tips the previous owner installed. I don't hate it. I haven't heard the Thermal to compare it to though.

Do you know if it has the resonator?

Installed a Vibra-Technics fast road RMM during an oil change. Now saving for the other two mounts, intercooler and pipes.

It does. It's not obnoxiously drone-y in the cabin and when it gets warmed up I get the occasional pop on closed throttle. Sometimes I think the tips are too big for the car and sometimes I think they're fine. I'd have to ask my wife if it's louder than the FSWerks exhaust on my old Focus (which I didn't think was THAT loud.)

I’ve been eyeballing the one with titanium tips for a long time. I don’t want to ruin the driving experience though.

Did a trip to Zocca, a small town in Italy to test the car and my obd reader. Yes you can check afr even with readers without hs/ms

Holy crap!

I just installed the Cobb exhaust on my ‘19. The previous over did a resonator delete with an AutoZone exhaust repair kit.

The Cobb exhaust is amazing. First thing I noticed is how much quieter it idles and cold starts. There’s zero drone, and the sound is much deeper and refined. The car feels smoother, but it could just be my imagination. Downshifts feels smoother and rev matching is easier. Also could be my imagination. I had no idea how much it would improve the car. I’m on the stock tune.

The hardest part of the install was pulling the polyurethane exhaust hangers off the stock exhaust. The install was super easy once all the old parts were off.

I’m planning on an intake, intercooler and a stage one tune sometime next month. I’m considering doing the radiator while I have the bumper off. It would be nice to have no overheating worries, because this summer in Colorado is shaping up to be insanely hot.
