have a look at my net address below, I have just posted some pictures where you can look the JL RH2000 and the Scorpion exhaust close to each other.
You can see the different shapes and you could compare with the new ehaust from beerace ( go to the forum to new pipes topic)

As soon as I get the beerace pipe I will do a driving comparison with Polini 207 and with a Malossi 210 both with tassinari reed and MMW manifold.
