Well for the money i will be getting a new Flexipipe, a new CAT and a new twin backbox and new piping from front to back all in stainless steel for the £487.
Now regrading to your post about my car only firing on 3 Cil...
1: my car is using a good amount of petrol im getting about 22 MPG but its all town driving.
2: the Car kinda spluttering but im putting that down to the fact that because my cat & backbox are blown my car is strullging tp push out the air pressure?

as for loss of power im still getting 109MPH???
