Ordered my crossflow from AutoZone, a Cherrybomb Vortex. Only cost $58.99, and it was definately worth it. Gives it a nice throaty grumble, still very little interior noise what-so-ever. Hopefully should have a soundclip up in a week or so...
(dont mind the crappy res., dont have a very good camera lol)
(vent visors too, hint hint hint)
I also painted my Pontiac emblem gold... it wasn't looking nice, and I thought I would make it match a little. I know, I know, not performance, but it'* a freebie!!
