So i bought a k&n filter and after trying the 2nd one I finally got the right one, anyways, before I put it on I wanted to see what it sounded like with out the air filter and it sounded amazing. Well I figured a way out to get that sound with the filter. i just took off the front of the air box and and placed some claps on the corner of the box to make sure the filter wont go anywhere and bam..sounds amazing. Its like a big high performance intake. Try it out guys or let me know what you think, cause that is what its all about. pics will be coming soon once i get back from chicago.
