There's a comparison between Pacesetter and QTP on a moderate H/C car. There's no other changes - just a longtube swap. There's a 9rwhp/7rwtq peak gain with an 18rwhp/30rwtq gain at ~3100 rpms.
You asked for proof. There is undeniable proof that all longtubes are not equal. That's a myth. Some are obviously vastly superior to others.
Were both tests done same day? Were the same set of results.. ie.. did you take the reults from the first cold pull and match them against the first cold pull? Then the second vs the second pull?
Unless your recording data and comparing it exactly your example proves nothing. A dyno will fluctuate 10-20 hp depending on conditions. A car will fluctuate on every pull.
So when your throwing numbers and graphs up of course you can pic and chose which set of results your going to show... thats the numbers game and everyone does it.
Show us some real proof with controlled testing.
We've already seen an example of chinese metals with the lsx block issue.
US uses 304 for a reason.. chinese made 321?? crap shoot if you ask me
you get what you pay for. Your either on a Pacesetter budget or ARH,QTP,Kooks budget.

Money talks in my book....if the XS headers work to 99% of what the other do, and are around half the price, I really don't care who welded them up. Like Order66 said, this is 2008, we don't live in a bubble - but hey if you guys wanna spend a lot more, props to you.
QTP all the time
