    4" to 3.5" sleeve
    4 hose clamps
    I have thought of doing this with pvc piping and a cone filter being the only differences.

    Also talk to the girlfriend about what she thought about the truck being loud. Apparently I was wrong and she likes loud trucks only thing is she says it doesn't look like it should be loud.............(to girlie?) I guess some exterior mods will have to come with the go fast save gas stuff hahaha I'm thinking maybe some 18's and slight drop and do some color match some stuff.

    I might end up going a little crazy with this thing...... I mean its totally stock and has sooooo much potenial like any other LSX truck lol
