Thinking about Electric cut outs

I have Dougs 2 1/2" electric cutouts on my dart

They are right behind the collectors with X pipe behind them

My wife loves them, they are open when we go into car show or cruise in

If I were building the exhaust again would run 3" back to the mufflers

When I was still in school a guy put some manual cutouts on his car and they leaked. But had butterfly flapper and cables run inside the car.

I didn't want leakers, Dougs use to be a knife blade type (what I have) they didn't leak, until a motor went out and I replaced the motor now that one leaks. I need to take it apart and try and tighten it back up

Was at a cruise in and a guy fired up his mustang and revved it up thinking it sounded cool, till I started the Dart, revved it up and he said YOU WIN, .......LOL
