Default Knocking noise?????

I bought a 2004 silver 6sp a few months ago and have a question. When I give it 3/4 to wot it starts to get this knocking sound, like valve knock. Only mods I have are a blackwing , de-screend maf (which I heard is bad to do now.) x-pipe and corsa indys. I use Cheveron supreme gas. I still have warrenty left should I take it to the dealer? Any thought would be great..

Check your code history. It might be running lean on one of the banks.

Put your stock MAF back on. I had a descreened maf on my trans am and it done the same thing you are describing. Put the stock back on and it quit that instant.
