Personally, I've never heard of them, but if they work without a bunch of mods, go for it. Are they long tubes or mids. They look pretty nice. Only thing I'd suggest is to get ceramic/titanium coated ones, as they keep the motor heat away from the wiring and other lines in the area. If they're SRT headers, they'll need to be modded so the 5.7 EGR system will still work. If you don't want the EGR working and if you have a DS tuner, you can get it turned off with a CMR tune.
yea well i have no idea wat the guy did and researched alot of it but nothing but the guy says right there that its a perfect fit that wat got my attention,and i searched the headers on google and i found them on couple sites for like 500-600 range...
Well, I don't know about this application, but I do know a little about OBX. Lots of people on my old GTI forum use their downpipe. Its pretty much the cheapest you can get. People always said the welds were very nice, but fit was iffy. OBX sells most of their stuff on eBay, much like Megan (if you heard of them). I would say just make sure you can return them. Clearence is really tight for us and as I said fitment was a problem that came up many times.
