Cable controlled exhaust cut-outs

well im guessin you would have to route it from under the car to the engine bay then through the firewall (kinda like the clutch cable). ive wanted to get a set of the electronic ones and use them for dumps after the mufflers instead of open headers but i have been trying to figure this all out for a good while now. just havent really picked which method i like most.

the jegs one is something that you have to go under the car and undo yourself plus its just like a massive exhaust leak due to it going out the back still then also wherever you put that "Y"
