There is a very simple aproach to this problem. its called: build them yourself:D
when you are done :banghead::protest::violent1: and are in a weird state of :blob::icescrea: you may get an idea about why these headers are so darn expensive.
And the answer is the same as the other countless times it has been asked. No matter how you work the question the answer will ALWAYS be the same.....open the wallet, let the moths out pay....or don't let the moths out and complain about poor fitment....and then a few months later spend the big bucks on the better headers because the cheapo ones are too smashed to use...
