...or is it the turbo and blow-off valve that I hear?
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.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.
post it for sale or trade on this here forum ... you'll probably be successful in a swapThis 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?
