exhaust cutouts, worth it?

think it depends mostly on how efficient your exhaust system is.


my car ran the same through the 3" X-pipe exhaust as it did with the cut outs open..




but also had a friens with little pee shooter exhaust on his car and he would get at least a half second drom the cut outs.. he has fill 2 1/2" tti exhaust now and i'll bet he no longer needs the cut outs.. not sure when he will get it back to the track.
