Long headers

Just wondering especially to those who have these, are they worth 700 bucks? And approx. hp gains?

Also if anyone can recommend a good intake system that would be great im just running stock now, and there are quite a few different ones, so what works good for you?
Thanks in advance.

Well 3sx is a good company, and you are pretty much getting headers + a downpipe, so yeah, since they just came out, I could see paying $700 for them.

As far as intakes, they are all pretty much the same. If I could do it over again, I'd get the really big K&N that Thourun has. It's the biggest one and costs half of what the others do.

Thanks, I'll have to check them out, esp since I have a NA I will need all the help I can get ;)
Ive read the NA upgrade bible too thats a good thread.
