So far all been good with the 5door run around. ECU now fully aware of the Corolla manifold and engine is much more responsive, but fuel consumption has increased by 10 miles for £20. Considering that it only has a panel filter and the manifold. Need to fit the exhaust manifold too. Looking to change the exhaust system too. I have a brand new Glanza V performance 2.5" system and will be easy to mod and fit, As much as I'd like to, I want a std looking system. So if theres any body out there with a good condition std system that wants to swap with money my way obviously. If not, I'll put a sports cat in it with an extra silencer and fit it.
