I just got mine in today and got it installed. It's deffinitly louder than my other Magnaflow exhaust system. For sound it's very deep, almost makes my car sound like a v6. Deffinitly the deepest exhaust I've ever heard on a 4 cylinder. Added power is pretty noticable from about 4000 rpm's to redline. The dual tips look good, but I was kind of set on the single 4" tip that I had on my old car. Right after I ordered it I saw the HKS and kinda wished I would've held out to buy it. For the price of this exhaust I don't think you will find anything better imo. I guess I'm more into a quiter exhaust though. Keep in mind I'm very harsh when it comes to an exhaust system. I think the sound and look of an exhaust system is just as important as wheels so take this post with a grain of salt.
