Just giving my honest opinion.
As for not affording headers... Ok lets price a bolt in DP and a Powerlog, and price a cheap set of ebay headers. There ain't much of a price difference plus you get way better flowing primarys and you upgrade the entire exiting setup w/ a good downpipe too. Theres really no comparasion. The choice is very easy in my eyes. Even for someone budget minded.
Sorry for giving my honest opinon, but a Powerlog/DP setup will get owned by the cheapest headers hands down. Dollar for Dollar, the Powerlog/DP is a half assed route compared to the cheapest headers out there. Thats my opinion though. Just telling the guy the truth. He can make his decision from here, he's a big boy.
I wish I had the options we have now and someone telling me useful info like this when I started this game over 7 years ago...
