yz250f t4 system

[henk zorro]

I'am interested in the t4 system I have seen in recent Pro Circuit Adds, but I have a few questions.
What's the noise level, are they FIM approved. Do you have a dyno chart compared to stock. And what's the best way to purchase them in Europe (Holland to be exactly).

Hi Henk,
I am from Belgium and i have a TI4(complete system) on my CRF450 '03 which works very fine (more power everywhere specially at the bottom).It's a bit loud but not more than a Rino or an Akrapovic ( european product ) . I don't know if they are FIM ok.
Maybe there is a dealer in Holland but i bought mine from http://www.freexracing.com/ in France . I don't know the Holland's price dealer but in France it was 1004 euros!!!!!!
Don' t pay too much attention to a dynorun cuz numbers can be arranged very easily and each bike are different ( it's what Pro Circuit told and i agree with them).
I hope this helped and see ya. :cool:
