Exhaust Install Question
Hopefully someone here has been in this situation, but I'm getting ready to remove my AWE exhaust and replace it with a Corsa Axle back exhaust. The AWE exhaust doesn't use valves so I remember removing the OEM valve control motors from the stock exhaust since they weren't used. Now that the Corsa exhaust has valves, the install instructions state:
Locate the muffler and the valve control unit removed from the stock muffler. Orient valve to match the rotation of the valve control unit as it was when removed from stock exhaust. Since I have no idea what the orientation of the valve control units were when I removed them from the stock exhaust, is this going to give me any problems installing them on the Corsa exhaust or is it much simpler than this and am I overthinking this process? |

Pretty sure they only attach one way, been a while since I swapped the ones on my '17 so many years ago, but I don't think you can mess it up...
That said, you could probably figure it out but just attaching the control unit to the muffler and toggle'ing it in the car and watching it. On a lift it might be tricky, but still doable?

I don't have any input to help you out...sorry. But I would like to get your opinion on how the corsa is in comparison to the AWE. Why are you switching? And if you wouldn't mind giving a review on the differences as you drive the corsa. Thanks!

I would also like to hear a comparison video on the Corsa if you could.

Was your AWE a catback system?

Yes, which brings me to another issue, I'm hopeful I'll be able to swap the axle back Corsa system and connect it to the AWE X Pipe. I don't want to have to buy a Corsa X Pipe to connect it if I can help it. I won't know for sure until I get the Corsa system tomorrow and get the car up on a lift to see if it will bolt on.

They only go on one way, so you should be good. But you could always key the car on with the valves plugged in and not installed to make sure they default to the correct position then install them.
You should be fine on the X pipe. I have my Corsa axle back bolted up to a Borla 60608 resonated X pipe and it all fit perfect.

I think once you shut the car off, the valves go back to the default position. Thus when I start my car, it defaults in touring mode (as the default)? So, I'd think the valves are in touring mode when no voltage is being pushed to them, the car starts up in touring mode?

Another question to ask is when you switch from one catback to another (different brands) is the "cut" you made for the original going to work with the new?
