i am thinkin about electric cutouts. i mean whats better than plain old open headers? :) but in the meantime i am gonna run max wedge mufflers from the accurate exhaust reproductions. but that list really says it all...
If you install cut outs don't use the ones made by QuickTime... they will not last very long... believe me. I could right a entire page of how many problems I had with just one on my Dodge Ram.
