Depends how tight your buget is.

under £100 << Decat and port and polish throttle bodie
and maybe £250 could get you a good 4-2-1 manifold and the above.

decat will be cheap and should free up a bit of power

not to sure if i want to go down tghe decat route is it not illegal. how hard is it to port and polich throttle bodies is it something i can do or is it a garage job does it make lot of difference. think im going to get rid of some of the extra weight at the weekend

its something you can have a go at yourself, the gains are only like maybe 1bhp if that, but your throttle response will be much sharper :y:

and no a decat isnt illegal, just need one to pass an mot.

decats arent illegal,, but theres a very good chance your car would fail an mot with no cat(not 100% but 99%) which means its tchnically not roadworthy. however you'd only be made to go and get a retest within a certain amount of time
