yes standard engine, k&N filter magnex exhaust holds 12psi, i might go zvh later down the line or maybe 1600 on cossie managment, i need to finish my restom on my rs2000 first though, then i can start on the rst..

like i said the only reason im thinking of changing it is due to the noise and wondered if it would be worth putting in a higher spec one. CheeRS
for your help..!
