Actualy, i didnt notice such a big diference as advertised. I am running an LRPz.28 spec 3 non pull start with RB header. I will try it for a few more weekends and i will get back to you.

Remeber you can also tune the pipe itself for low ens punch or higher top speed. Also try out the additional springs that come with the pipe. If you still have any issues call them they have great customer support.

yeap, by nowi only tried two springs. What engine are you running?

Iwas running it on the TRX 3.3. Im actually going to purchase another one for my OS .21TM. My original Buku got demolished when it was run over by a real car. But I was more than happy with tthe performance.
