What else can I do for Louder Turbo

You can port the intake horn flush, and put an aftermarket intake for louder whistle. you could also get the batmowheel to replace your stock wheel

i sorta made my own intake. i found a spectre intake for 78 bucks on ebay, and replaced the shity spectre filter with a good 8 inch AFE dry filter. turbo is way louder with the window down. not a whole lot louder with it up.
