Was reviewing the install instructions again from Corsa and noticed something that may be fairly important (though still unclear).

See image below:

See how step 2 mentions that when you are installing the valve actuators into the exhaust, that you have to make sure the valves in the new exhaust are in the fully open position? That would make you think that when you turn the car off before starting to install, that you should have the exhaust in the open (loud) position, because the actuators would be ready to go into the Corsa, which is wanting you to install it with their valves in the open position.

Thoughts? If you turn it off in tour (quiet) mode, and then install this way, the actuators would think the exhaust valves are closed, but you are installing them with the valves open.

TapOut’s install disclaimer also says to shut the car off in the OPEN position. That’s what I plan on doing, along with making sure they’re open when installing in the new exhaust. Unless you tell me otherwise. Mine still hasn’t shipped. But I think as long as they come out either open or closed and you reinstall them the same way everything should be fine. The car should remember how they were the last time the car was started… at least you would think. I plan to be super meticulous with this step to ensure they come out the exact way they go back in.

Let me know what you do so I can repeat it.

Good luck! Let's hope everything works!

 

[5VBW Nick]

Done . It's awesome. I will make an in-depth post later with important tips & info for installation, along with my thoughts.

I’m eagerly awaiting the write up. Any CEL?! How big of a pain in the ass was the install? Did you need a grommet puller?

Does the “quiet” side of the pipe go in after the valve? How does this work? Wouldn’t it block ALL flow when the valve is closed?

 

[5VBW Nick]

I'll write it up tonight, busy day today. No CEL, did 99% by myself in about 3 hours. You really need the exhaust hanger puller.

Yes I know, I want to type it up and share. Been so busy with work this week, but I'm still trying to find time to put it together. Let's see if I can get to it tonight

CT5-V Thread 'Corsa cat-back exhaust installation tips & pointers, along with my thoughts/review (short video included)'

Apr 16, 2025

Well, I finally had the time and weather to install my Corsa cat-back exhaust this past weekend, and I wanted to share some info I feel is important regarding the installation. The install itself isn't anything too difficult, but some parts of the instructions need to be clarified, some parts need to be highlighted to ensure a smooth install. I'll try to keep it to the point, but these are my thoughts as a former Porsche Master Tech and car guy that has been wrenching for 30 years, mostly for hobby.

Critical tools:
Torque wrench - you 100% need this for torquing the exhaust clamps...
