yes! for a more agressive sound the open flaps are definitive a must have ;-)

normally the flaps opens at a certain rpm!

its very easy to open the flaps, you can just lock/fix them with a little screw. thats it. tooks 5 minutes!

your can also do a different mod if you cut off the hose wich opens the flaps: http://www.e90post.com/forums/attach...1&d=1183338204

but I dont tested it!

but for a better and more agressive sound, the open flaps are a must have
