I have a 2009 Mazdaspeed3. Already had a downpipe/racepipe installed. Installed this puppy and it was a whole different story... took about an hour to install, (i'm a novice). Once I put it on... typhoon is right. It sounds like a tornado under my hood. They claim around 20+ horses, and I'll tell you what, the last thing I expected was anything more than 5hp. (I'm realistic). I definitely got 20. Wheels spin through 3rd gear, car screams all the way into red. Solid sound, killer performance, looks badass under the hood. My first K&N product. if I could give this 6 stars I would. Absolutly fantastic product.
