when i first got my buick this was the first thing i upgraded. it was cheap and seemed like a good deal. i now wanna up grade to some performance headers and was wondering if anyone else is running this downpipe and what brand headers work with this dp i dont wanna make the mistake of buying some that might not work. i hope im not the only one i did a search and found nothing but bad threads about people not getting their downpipes from the owner of the company
