why? because its badically made of the same stuff as a coupler? thats no reason to laugh.. do u know how much work goes into getting it molded right and then having the ports molded into it.. and if it helps make more power id say its well worth it.. say it gains 3-4 hp.. and its $150 you guys will pay 400-800 for a header to gain around 10hp.. Now who do u wanna laugh at? u would get more bang for the buck outta this.. it could also help with A/F and drivability over the stock tube.. dont sell something out just cause u "think" its not worth it , when u know nothing about it... Vw guys have been running stuff similar to this for years and noticing good gains...already laughing at anyone who pays 100+ for this, in advance.
Consider this my pre lol.
