all go 7 port owner hear this!!!

i raced the engine for 3 gallons with nova 9886 pipe and liked it very much.
today i checked other pipes as i needed an efra approved pipe, and when i fitted a rb 2045 and it origianl header (rb 192), me and the other racers was shocked!
excellent top end, and unreal bottom, it was like a very very powerful short track engine with the top end of large track engine. i'm a very good driver and it was to much for me.
you should try it!!
