fuel consumption gone up!!!
#2
Hi Fosters,
can't really give you the answer but the same happened to me, increased mileage after upgrading the exhaust to a decat 3-inch full system, seems too good to be true, power, music and MPG all at once
If I can resist the temptation to step on harder, that is.
By the way, with the OEM system i get a full thick blackish coat of carbon deposit over the muffler tips. With the new exhaust it's more grey than black and much thinner. Healthier looking i guess. So maybe running leaner accounts for the additional mileage?

Fuel consumption will improve when cat(s) are removed as the cats take up a fair bit of the engines energy. Therefore like for like consumption will improve. My weekly motorway commute figures improved by 3 or 4 mpg
DISCLAIMER - with more power leading to more temptation of the right foot, figures can go down as well as up

Sorry guys, misleading title! my mpg never got above 24 with a cat'd system, now it's 25. Although, now getting used to the noise level, so I should imagine it'll go down again!!!
