Currently i have a ct9 at a bar, standard ported mani, decat, 5zigen exhaust, front mount filter, front mount cooler and an emanage blue. Im running 168bhp. I have 2 choices. Buy td04+ mani+ downpipe. See about 220bhp on standard internals with more lag (cost 600 quid plus mapping 120 for 2 hours) Or go hybrid+ new manifold and hopefully see 200. (Cost 250 + 100 ish + mapping bou 60 to 120 for for 2 hours) Im swaying towards ct9 as this one is in real good condition
