Sport Compact Car rated the DC 4-2-1 the best for the GSR because it gave the best across the board gains.
The stock header is apparently pretty good when matched up against alot of the aftermarket stuff.
Like Jngrbrdman said, any help to the flow of air helps, but you get the full gains from it unless help the flow in all other areas of your exhaust....
