Installing SPD downpipes on 2020 Explorer ST 

You need a 17mm 12 point deap socket a swivel, a long ratchet for leverage and I used 2 12" extensions. I would recommend all 3/8's drive crome - no impact sockets. On the passenger side right bolt you have to pull the swivel back to turn everytime the swivel binds up! I would do that one after the left nut is off, but when you install the dowpipes tighten the right one first. You can see the right nut if you remove the lower cover in the wheel well where the O2 sensor plug is, or swing it out of the way. That's the only way you can see if your on the right nut on the passenger side downpipe

Nope

You don't have to tune for it, but you'll get more potential if you get a tune or revise your current one, once you install the downpipes.

Are you talking about the nut on the passenger side downpipe right side closest to the frame?

@@SouthdownGarage I ended up getting them free, with a lot of penetrating oil and patience. 😂

@@mortysrick2111 yeah, the one on the right is a nightmare. But at least you only have to do it once 🤣

It's just exhaust heat wrap that is installed on the headers. Yes there are gaskets between the turbo and the downpipes. I ordered them, but the gaskets are metal, and I did not replace mine.

@@SouthdownGarageis the wrap needed or optional?

@@dragon0361 Optional but a good idea. Whoosh actually sells a shielded downpipe for the ST

I would imagine you'de be correct. Kinda jealous on that point!

Yes the do sound completely different in person. The spd downpipes don't have as deep of sound.

I haven't switched to the test downpipes yet. Still running the catted ones. I sell CV Fab downpipes, I stand by their quality. You'll be happy with them.

@@SouthdownGarage ahhh thank you, thats def reassuring!!! Cant wait to install them myself. Thats why I was watching this video. But I have no lift just jacks so pray for me lol

@@SouthdownGarage also you think those flexible extensions would be any help here for the downpipe bolts?

I did the first time because it's really hard to find the passenger side downpipe nut, but you don't need to. If you put a 17mm deal socket with a swivel on the nut closest to the frame you'll be able to get it off without lowering the transmission cross member or subframe. I'm not going to lie, it may seem impossible at first, but if you unplug the lower o2 sensor there is a plastic piece cover were the plug is mounted to the body, you can look up and see the nut from there. Hope this helps.

Your engine blew?

What happen???

????

Lmao

I'm in BC, Canada

Should only take 4 hours total for both cats from a shop thats done it regularly. If you were near BC Canada i'de do it for you. It's not fun taking the passenger side downpipes off. So you'll have to be really patient. Drivers side is way easier.

They should, they are high flow cats. But always good to check with the manufacturer.

@@SouthdownGarage thanks for the reply!!!!

@@blakegarner3719 no problem!
