This is a race with all sorts of exotic classics, of course, including Ferraris, Porsches, etc., all known for their exhaust sound. I had to admit that my favorite two cars running were two Mustangs - very distinct, smooth, yet screaming/ripping sound - almost Ferrari like! But, better in this case. The other Mustangs were nowhere near as smooth or ripping - "just" your garden variety booming race V8s. We later found the cars in the paddock. Both were side by side in the Edlebrock tent. We spoke to Vic himself. He said both of them had X pipes that they developed. He said that he did not believe their X pipe (or anything close) would fit in a Tiger. But he added that the X pipe is more for higher racing rpms, while the H pipe probably sounds better for street rpm ranges. </div></div>
