I know exactly what you mean about keeping it standard, and thats fair comment

but as i use the car everyday and the old exhaust was starting to look a bit tatty, i thought a new exhaust makes it look a bit nicer. Its not getting any more engine mods tho, as i like it just the way it is
As for tyres, its got Michelin Pilot Exaltos on the back, and Goodyear eagles i think they're called on the front
