My bad I didn't know What about an exhaust? Any preferences?
I'd listen to advice from others on here when they say... don't bother spending the money on the 1.4, the power you'll get for the money you spend will be terrible. I'd focus on looks/handling if you really want to, but save for a much faster car as standard. Long term, you'll regret the money you spent on a car that was never designed to be very quick. That being said, it's your car, you do whatever you like to it. Many will say, don't bother modifying a 2.0 ClioSport, save for a 911 etc.
