I've done a bit of a cheeky today and gone and disconnected the pipe from the cat just under the passenger seat on my TB42e.
I like the sound, and that's all I've done it for, but I'm wondering if I leave it like that will I regret it.
Am I harming my power or fuel efficiency?
Will it suck up water?
Are the fumes gonna do any damage?
