iman16vw sold me his used brospeed header. it is sweeeeeeeeet. i put it on this friday. it gave me some gains mid range and up top. i hope to get it dynoed this week sometime. even if i bought one new, it would be worth it in my opinion.
my car pulls/revs so fast now, its almost like the tach cant keep up
I would buy the Brospeed header. I have a supersprint and it is not that good. Bellevue MotorSport, BMS prototyped a header off of my Scirocco and it worked considerably better. They are not in business anymore though. My friend did the last prototype US fitment for Brospeed and his car made really good gains across the board. I would buy their whole system, it worked the best when they did the testing.

how do you figure? headers wern't really designed to flow more, they were designed to change the flow charactoristics, to smooth out the engine and make all cylinders run the same.. adding any thing down stream of the header isn't going to make a diffrence in the way the header performs.. it may change to over all flow rate of the exhaust, but the header will still do its job.
Also exhaust systems are tuned to work at peak effeciency with a cat in place, engines need a small ammount of back pressure, with out this they run rough and lose torque. If any one can show me that a basic aftermarket exhaust system will show large gains of HP and torque over the entire band with out the cat I will change my additude.. untill then, removing the cat is a illegal waist of time.. High flow cats are the way to go IMHO.
Actually when you need to reduce unburned HC, NOx and Co a properly design cat works very well with a header. The BMS header that was prototyped on my Scirocco had a cat and made more Hp. and torque than a Supersprint header. So to say "Any header that keeps the cat is pointless. It may look nice but its defeating the purpose. " is not quite accurate. It would really depend on the application.
