well i wanted a couple opinions on what my next mod should be...

i am either going to do tint...but i dont know if i want 10/15/20% all around or 20% in the front, 5% in the rears...

or i can trade my muffler for a evo2 axleback

or invest in a header because i have a GS-R header on my motor right now...
