318 exhaust cutouts

It's very cool. However in comparison to headers. In my opinion, headers do sound pretty nasty. manifolds will have a different tune, thats for sure. But hey if you like it, Run it!! they are very cool to have. video from my digital camera doesnt quite do it justice, still kicked a 1.9 60ft at the track with open 3" exhaust and 5,200ft elevation. Little 318 doesnt seem to mind all that much.
