Turbo cars love cold air, especially after a remap so I like to go with a better intercooler and pre-cats also hold heat in near to the turbo. Main cats aren't such an issue as they are further back so the gases have cooled.
Spoke to a mate today and he said Wagner do some stuff. Downpipe and intercooler.
Anyone know if they are any good? I'm undecided on tuner also. It won't be a basic remap with the pre-cats removed. I would think they would need coding out.
