   what engine etc...not too sure on MPG could probs work it out but sick of doing uni work tonight lol it will give a better flow of zaust gasses so will be a slight increase in bhp but linked with other breather mods it is a good mod.. it will also change the exhaust note if linked with a sports system such as magnex etc...
   it will probs increase throttle response and flow through the rev range
   
   im sure if im wrong some one will correct me but im pretty sure that about it. i aint done it yet as i only have a 1.1 with cat in my manifold but im doing a vtr convertion and it the first thinking i'm doing after an MOT tho as it wont pass emitions with out one

   no probs mate i think the VTS is under the car cat and so a small straight through insert can replace it to free up zaust flow basically

   It shouldnt really make much difference to fuel economy but if its louder and pops and farts your more likely to drive it abit harder to get it to do it which is where your lose your mpg.
   
   Dont forget your need the cat for the MoT so tuck it up somewhere warm with a saucer of milk till you need it again
