i say go for long tube headers... maybe dynatech? the sound after the add will be amazing... i think, and they do add hp...

Now I am not saying that they don't add HP but they might not add as much as advertised. If you do get them make sure they are 304 SS. I do like the ARH and they are 304 SS.

Yeah....I'm going to wait and do a LT header and Xpipe combo.. I plan on American Racing, Dynatech, or Kooks. And i'm probably going to go 1 3/4

The headers they installed in that article are the Macs, which are only mid-length headers as opposed to true long tubes, and I have heard before that they don't get you as much power as true long tubes like Dynatech. And they went with a hi-flow cat setup, a lot of people go off road which should be good for another 5 horses. And maybe the resonators cost a few HP? Also, they admit in the article that the weather was a lot warmer. Not saying LTs are a good performance boost for the money, but 20+ HP seems reasonable despite the results in the article. Then again, they had a blower which would probably give you more HP than N/A.

You would be correct in that assumption.
