Exhaust Cutouts

[jmanley]

I have electric exhaust cutouts on my 72 Mustang, and I use them for racing (and occasionally freaking out the rice burners). It is NOT appropriate (and illegal) to use them on the street. I use them mainly at the drag track.

One more thing to consider - when opened and free-flowing, you're H2 is going to run lean - how much depends on RPM and where you install them. It can be dangerous to your exhaust system.
