Well your question still hasn't been directly answered has it? No sense letting your thread end yet.
While it may seem natural to want to equip mild n/a cars with the same headers the guys with 9 sec ETs or big dyno HP have, what they use often doesn't apply to the average owner. In fact the magazines are always warning against it, and what Tony's alluding to in his replies.
Over the years, reports from Belanger headers users have been consistently positive regarding power gains. Whether that means they're the best, or only that there are more Belanger headers out there that the other brands is hard to tell.
On the other hand there are other ways of getting very nice HP gains out of the exhaust even with the OE exhaust manifolds still in place. I bought a set of used Belangers earlier this year, since used ones don't come up for sale very often, then later sold them again without putting them on after realizing I'm already making at least as much HP as any header catback combo I could buy-so why increase my costs for no gain?
So much so that it looks I'm going to have to get a tune one way or the other to counter a now way to rich Open Loop problem, unless the one inlet side mod I have left to do can counter the richness via the additional airflow.
