I was wondering if it is a good idea to have a double electrical cutout with my mods for performance reasons, or they would be for the reason of scarring the neighbors .If I would get a double electical cutout setup, I would have to save up some cash. These things are not so cheap. I was wondering if it is a worthy modification. How it feels when you open both up? Probably they make your car shape a bit and give some ideas to the driver next to you about what's about to happen

 

The answer to that question: the car will be incredibly loud (the word deafening comes to mind) While you may or may not like that, if you get the electric ones, noise shouldn't be a big deal, you can close them any time you want. Now as far as performance gains go. Our car club had a dyno day, and one guy who had dual cut-outs on his car gained 13rwhp/13rwtq after opening both. And gave the dyno guy some ear damage. Another guy who had a single cut-out also gained 13rwhp but 8rwtq. And his car was much more mellow sounding compared to the other one. Hope this helps, good luck to you.

 

Not like I know for sure or anything but with you already having true duals I don't think you would see too much hp to be gained. Maybe 2 - 5 rwhp . I'm sure someone else more knowledgable will chime in.

 

Oops, didn't see you had true duals. I agree with hysr then, I wouldn't waste my money on cut-outs, save it for something else.

 

My true duels keep hitting the ground, so I am planning to switching to a Y pipe with two or one electric cutout.
