Deep, rich, and elegant is in, loud and obnoxious is out

Deep toned and meaty, but still classy and smooth. The stainless looks as good as it sounds. Took about 20 minutes to install, but in all fairness I had it on a lift. 45 minutes in the driveway with some help would be an acceptable estimate. My only complaint is the price, but it`s not autoanything, it`s the market. These guys actually had the best price on the internet for it.

Quick and Easy

Had it installed at mienke for about 200.00, took about an hour and a half. As soon as I started it up I noticed the difference immediately, deeper growl and a little more pep, which is saying a lot as the speed3 is already pushing 263 horses. After the CAI was installed it was on, after about 60-70 miles I noticed the growl getting deeper and the car was faster out of first thru third. As the old saying goes haven't turned on my radio for about two weeks now! Excellent product, one complaint though, the driver side tailpipe sticks out a little more than the other side. Other than that it's a great value at the auto anything price and free delivery. If you have the means or the good credit I highly recommend this exhaust system.

Great System

I have an every day driver and I wanted an exhaust that sounded good and had performance improvements without the "rice burner" sound and that is exactly what I got! The sound is great and not too loud. My car also improved on gas mileage by over 2MPG! I am very satisfied and would recommend this product to anyone looking for an exhaust that is not deafening loud.

This system sounds just slightly deeper than my Mazdaspeed3 stock exhaust, and looks better in the bumper cutouts. However, the left side tip sticks out about 1/2" further than the right side, and I'm having a hard time looking at it. Aside from that, the fitment on the hangers was straightforward, but overall I don't think this is much of an improvement over my stock exhaust.
