Loud tweetering noise
The install took about 2 hours (I don't come from an automotive background) wasn't too terribly difficult thanks to a YouTube video I found which walked me through the install. There are some noticeable gains in HP but the biggest downfall to this product with the loud & obnoxious tweetering/reverb sound the intake makes when you are accelerating hard over 3/3500 rpm's. I'm likely going to take my car to a performance shop to see if there is anything they can do to correct this sound.
No Complaints. It's just as described.
It was pretty easy to install. I just took my time and did it in the driveway. There was enough assembly to let me feel like I was doing more than plugging something in, but not so much that I had to buy special tools or consult youtube videos. I can hear a difference when I accelerate. The sound is somewhat of a hiss and not a deep growl like we hear when we install one of these on a V8 for instance. I like it though. I notice additional speed and power, but it's not real theatrical. I just look at the speedo and am surprised that it reads 80 already...that kind of thing.
