exhaust / induction again sorry but its relevant

[midcuk]

right im ordering a new exhaust induction kit in the next week
do i go for the tried and tested xpower duplex and itg recommended route and spend a fortune or do i go another route

my other choices are blueflame or powerflow for the exhaust and not sure about the filter

i like the idea of the itg because people state it makes a difference from right low down the rev range where as others you only feel the benefit higher up (and i keep revs low most of the time as im a slow driver) so the itg would be beneficial where as it costs a fortune compared to others
dont want to do a diy inner wing because im a tool and would screw it up so would prefer off the shelf so to speak, been looking at bmc, viper kn filters all a lot cheaper than itg also powertec filters get a good review have any of you got one (they are cheap as well on potn)
basically want low down useable torque and the itg seems to supply this but at a price

recommendations please ?

ps im going to put it on finance so a small difference in price isnt going to be that much of a factor rather have the most suitable.
