tbh the janspeed manis are only worth a couple of bhp, this has been proven. i personally wouldnt spend that amont of money for a few bhp.
i may gain 2 bhp by putting manifolds on but will loose that by putting a sports cat on over a decat.
iirc ross and kev both had identical mods, one with manifolds and a sports cat, and one with standard manifolds and a de cat and de-cated with standard manifolds car gave 2 bhp more.
