on the safely modding thread it says if you get headers you dont have to worry about the ubend/downpipe or powerlog. are you guys talking about these headers?

PACESETTER Header PONTIAC Grand Prix GTP 97-03 70-1205: eBay Motors (item 300434309520 end time Sep-02-10 09:04:49 PDT)

or these headers?

97-03 PONTIAC GRAND PRIX SUPERCHARGER RACING HEADER 6pc: eBay Motors (item 170469647572 end time Sep-03-10 17:40:53 PDT)

or both will do the same thing?
