Tapered Vs Powerbomb head pipe

Ok, new guy has anouther question. I understand the theory behind the taper disign. Does the FMF powerbomb actualy work? Does one produce more power than the other? Will I notice a change in power with this mod/upgrade?

According to Paul Krause, the Powerbomb does increase power everywhere. Runs quieter, too.


Yes, the PB works!!
