Stainless steel race decat exhaust system and manifold + Induction cone with heat shield + Evolve Automotive remap :) its what ive done so far,jobs a good un My next power mod is the best pound for pound mod is to get an m50 inlet manifold conversion and big bore throttle bodies....it adds up to another 30bhp so either of the 2 above options,the latter is the cheaper :) hope this helps
