Check the back firewall for an opening under the black felt in an almost straight line back from the spark plugs (driver's side). I tried to add a couple pics to help locate it, but my desktop has updated and now I can't do shite! If you've got one and Chevy has simply plugged your intake opening (as in FarmerFran's car), I'm betting it is cheaper to plug and just cover the hole than doing away with it.

I'll try again with the pics- sorry.

BTW- this is not just a hose to carry sound into the cabin. It's got diaphragms and other components to protect you from fumes/ carbon monoxide, etc...

Sorry, I know you meant full throttle and autocorrect messed it up, yet I couldn't help but imagine a "full throat" acceleration

When I want even more volume than what NPP provides with the valves open, by the way, I drop down the rear seat. That's my cheap "loud exhaust fix" for five minutes, then I realize it's been enough
