In all this discussion about CELs and extended tubes, etc., I think we've glossed over something else that's kinda significant. Stillen claims less of a gain on their HFCs than Berk. Although I must say, their web page for the HFCs is a tad confusing right now, because they claim only +9hp and +8ft/lbs tq. Yet, when you open up their dyno chart (for a G37), it shows +16hp and +13ft/lbs tq. In any case, they're claiming less gain than Berk either way you look at it.
