If you want a bit more sound remove the intake snorkel. Takes 10 minutes to remove and just as much time to install. Doing so will give you a bit more intake sound which on this car is pretty sweet sounding.
I did a under drive pulley and the secondary cat delete (not sure that the European cars have the second cat but this delete adds a little power). Between the two I maybe got 5 to 10 hp on the top end. After to day of driving it with these mods I got used the tiny increase in power and don't really notice it anymore.
BTW most aftermarket mufflers are going to give you drone. Look into a PSE exhaust mod for you factory muffler to give you some nice sound.
