    NR-Racing headers on DB30???

    Sorry to start a thread just for this. Does anyone know if this header/exhaust pipe will fit a DB30? I know it will fit the HF 6.5 clone which i have but is it compatible with the DB30 frame. Is reforming/bending required or is it a bolt on and go? (sorry if the pics not there,new at this.)
