Suprised me this did!
I refitted the cat to my exhaust system this weekend. MOT is up soon, and I wanted to see what difference it makes to the car in terms of response, MPG and noise. It will be staying on post MOT too - I think there are other areas of the system that are a much greater restriction (I think one of the Kiwis has found this out).
To put this into context, Ariadne is standard as far as I can tell. No boost alterations, and just a HKS filter in the standard airbox. There is evidence of some other tweaks around the car (spotted a crudely terminated cable this weekend) but most look like they were removed (or stolen, more commonly) on the way from Japan to the UK.
And the results? Well, it's early days, but So far:
Noise - Slightly quieter and a slightly smoother exhaust note at idle. But nothing major.
MPG - Too early to tell.
As for performance, I reserve judgement untill the ECU and gearbox have stopped operating in eejit mode (I reset the ECU). As with my V6 Sport, I think it will take a day or two to see what effect it has.
I was surprised though by the lack of immediate change - I'll post more as I pile on the miles (In my fully Amsoil-equipped car :smug: )
