say a 2.5" catback gives you ~20hp gain over stock, a 4% loss in power gain would be less than 1hp, give it a rest....
SpecialtyZ's designs are completely different than Megans. One tenth of an inch does nothing for performance, it's the superior bends, longer runner lengths, better fitment, and better materials that make Greg's parts superior, not the extra tenth of an inch in diameter....
600rr needs to give it a rest. If he wants to gain an additional 1hp he should look elsewhere and leave the name bashing alone.
