Why you say i have no idea?
because i rather have a cheaper header that does the same as a $700 header that makes 20Whp or $1500 that no one has i think. i now parts are rare for are cars but but that's like taking advantage of the opportunity now that there's more competition i just hope maxworth makes it cheaper around the $300 or less range. a header doesn't need all that shiny steel for it to work you just need a good design and now what you are doing.
and as soon as they are available i would buy one depending on the price as long as its not out rages prices. But like i said i would contacted them when there out to see if i can get one that has the option of screwing my stock heat shield on
