I have an idea for a exhaust cutout for my truck.
I purchased the cutout alone. No electric valve. In the future I will buy the valve, but I have some college bills to pay... so the valve will be sometime during next summer.
In the mean time, could I just buy an extra cap, and drill a massive hole in it?
I'm wondering... would it whistle? would I get brain damage from the fumes?
I would like to have the opening facing the drivers side. Is this unsafe?
Would having a cap with a hole in it cause any flow issues?
