No worries
no harm has come from it and I'm sure it can only make the induction sound better. The rest of the intake will be removed as soon as poss anyway to make room for the CDA I've ordered and the custom hose which I can hopefully get made.
The catch tank wasn't doing any harm either, just wasn't doing anything really.
As expected, the exhaust sounds incredible. Seems to have a bit more torque low down since fitting it as well as revving much more freely.
The sound doesn't quite fit with a car that essentially looks like a Rover 45 with a spoiler to the un-trained eye, very 350Z like.
