Exhaust cut outs?

I have my 383SP GM stroker 445 HP and 700R about ready to install and am wanting to add exhaust cut out or dumps to the system for a few reasons some of which are childish hell I am only 50 and others for performance at its best.
Are there any manual cut outs that don't require trusting an electric motor to open and close the gates? I feel like that motor with the heat in the area might be a constant source of maintenance?

So far this is the best I have found any opinions or better options will be appreciated. Thanks PG

Yes cool thank you I have only seen electric ones that seem like they would be prone to failure?

Thanks PG

Yes, failure! I've had 3 or4 sets on my Camaro and I keep blowing out the seals, but they are mounted 2 feet after the cats. My son and I are trying to build graphite seals
