What I want to know is if the Borla exhaust is significantly better then the stock SVT exhaust with resonator replaced with a high-flow muffler. Both are stainless, 2.25" pipe, with dual outlets, right? Where's the advantage?

Way back when, we saw a relatively stock SVT with a KKM gain 8hp when the Borla was added. One point to make is that his before runs were when his SVT was relatively new and his after runs were performed after a lot of miles were added to the car. Also the runs were done months apart, as seen by the temperatures. Forgot to mention that he did have the resonator removed and a glass pack installed on the before runs.
Here is the graph.
