Hey guys, kicking around the idea of getting some headers for my truck. '00 1500 4wd rcsb with an '04 LM4 5.3L in it, was wondering if the 07+ headers found on ebay would work in these NBS trucks... They look a whole lot nicer without the goofy hump and the merge into the collector looks a bit smoother. Anyone done this? I'd like to hook them up to my stock catback. Thanks.

 

No one has done it, to my knowledge. I considered it, due to the nicer and larger primaries, but the hook up to the stock catback is unknown. The headers and Y pipe should fit just fine.

 

Just get pacesetters or LLP's...
