That website sucks heavy! Loooks just like a friggin puzzle. Some written info would have been nice, not a bunch of very small pics.
The VM headers are a 4-1 design. The Evolve are 4-2-1. Typically a 4-1 design will give you more power up high while sacrificing power down low. The 4-2-1 tend to give a more equal power growth throughout the rev range I believe.Are they the same as the evolve ones,any differences?
Raikku, you know you need never apologise for having an opinion on here, and I appreciate that from an engineering perspective you know far more about it than I.Sorry to come on here,but have to put a few things straight.
At the end of the day,tastes are different. Everyone likes different characteristics of engine response and behavior.

More Vanmannen bashing on a thread that is solely to do with Vanmannen, i really dont think other ie (evolve staff) should be commenting or evolve lovers (wkd) be pushing someone elses product on a thread that has nothing to do with them!!
Just my 2penneth worth and yes i have Vanmannen headers but i dont go on evolve threads banging on about my headers!!
