Re: electronic exhaust cut outs
SO I am interested in this also, from my searching i was leaning towards Dougs because of the mechanism, its more like a gate. I saw the QTP ones when I was first looking, they look good, act like a butterfly valve. I believe Pypes makes one also. These are the three I have seen, and again I am leaning towards Dougs but would be interested in following this to hear of any other suggestions.
Currently I am running them open, it sounds awesome, but would be nice to close them at night or near the house. Another idea was to have the Holley control it and open it up above a certain RPM...still thinking about that one.
