Its the turbo you hear, the only way to make it quiet is to put the stock intake back in place. GM did a really good job at making a quiet intake for this car, only thing an aftermarket intake does is add noise.

and maybe a little better miles per gallon if you can keep your foot off the pedal because you like hearing that whoosh sound so much :grin: I definitely noticed better throttle response from a dead stop with an aftermarket intake ... and I'm pretty sure it wasn't just my "butt dyno" making that determination.

This used LTZ came with the Typhoon. I don't need the noise. I'll look around on Craigslist to try to find the stock air cleaner kit. Anyone looking for a Typhoon intake?

post it for sale or trade on this here forum ... you'll probably be successful in a swap
