Wanted - Set of Electric Exhaust Cutouts

I keep looking on my doorstep too, but no one is giving away a set over here either. 8)

I'll probably cough up the $300-odd dollars for a pair next winter. From time to time a set shows up on e-Bay, but again, no one is giving them away. I've thought about trying to make a set from Infiniti traction control solenoids from an early 90's Q-45. They are nothing more than a throttle block that closes off the air intake... effectively cutting back the engines power. I was thinking they could block the exhaust.

I have to look into this....
