So let's say you bought an exhaust system for your ST. You excitedly take your car to the muffler shop or jack it up in your garage to do the swap.

When its all done you start up the car for the moment of truth and it emits a lovely sound or not.

If you hate the sound, it is too loud, it drones too much on your commute, your significant other complains or you have to sell/return your lease, etc. you can have a Plan B: put back the stock exhaust.

The stock exhaust is 55mm tubing but you have to cut it to remove it from the car without dismantling the rear suspension. Replacing the stock exhaust seems like a simple problem but finding a 55mm exhaust coupler at a reasonable price is non-trivial.

At first I thought Torca had one, it was listed on their product chart but its vaporware, if they actually make it, they won't tell me where I can buy one.

After that I eventually discovered that some VW and BMW use 55mm exhaust and OEM couplers are available but the cheapest I could find was more than $40. To that I say farfugnugen.

Doing a Google image search, I found something similar to the OEM pieces for $11.75. That's a reasonable price for Plan B.

The part number is 1K0253141M at autohausAZ.

I hate paying as much for shipping as for the part so I bought seven to get free shipping.

If you need a Plan B, let me know, I might be able to get one to you for cheaper than the retail price plus shipping. If you are local to the SF bay area, we might be able to meet and avoid shipping costs.

I hope everyone gets an exhaust that sounds nice and never needs to be changed but I like being safe so I got Plan B.

Just reassemble but it doesn't require welding, pipe expanding or tools beyond an appropriately sized wrench.

I think most performance downpipes will bolt to the stock exhaust, this is just plan b to restore your stock cat back after it has been cut.

If you are keeping the Stock exhaust make sure you treat it with some type of rust and corsion inhibitor as I took mine off in Jan and tossed in the shep only to find a pile of rusty corroded cheap stainless exhaust on the shelf when I moved it this weekend .. talk about poor grade stainless the pipe and res/muffler were covered in rust and a white powdery groth LOL gotta love life in the salted road country up north LOL

good find on the coupler! I bet it will be something that gets looked up a lot in the future. Finding the right exhaust is always hard. It took me 5 years to finally get it right on my Focus ZX3, and then I sold the car a few months later. Sucked to finally get it right, and then sell it. I don't know what exhaust I will install on the ST. I am going to listen to a few of them in person before deciding to make sure I don't end up with something that isn't right.

RodMoe, I am doing some corrosion testing at work after finding out from customers that some cities are now using a salt mixture that tends to stick to metal and continues to attack the steel whenever moisture is present. The parts actually rust all year long due to the salt mixture sticking to the surface. Getting the mixture off the parts is really tough. Isn't living in the rust belt fun :(

Spraying a LOT of penetrating oil will probably be part of my storage plan. There will probably be a lot of smoke if I ever re-install, but it's better than rust.
