I've got the CS cat back and I love it, the sound is really deep and throaty, you feel more power with the removal of 2nd cat, the finish of the exhaust is 1st class, meaning the polish and shine is real quality. I also have grown to love the "stealth" turn down pipes, they follow the original design mazda decided on when making this gen. Drone....??? I feel a lot of folks get this wrong? On highway doing 130-140 kms/hour in 6th gear yeah you hear that you got a really good aftermarket exhaust, doing 100 - 120kms/hour in 6th gear will produce drone.
My point is after you've driven with a good aftermarket exhaust, you get to know where all the sweet spots are? Also for people with AT driving in auto mode will obviously hear more drone. cause of the trans selecting up a gear for fuel economy, this is why I only drive my GT in manual mode, I also know what gear is best due to driving conditions.
Now I've had the Racing Beat axle back and I ultimately didn't like it, it barely sounded more than stock? So I sold it. I've heard the Magnaflow exhaust, and I liked it, sounded good, but for a cat back that doesn't remove 2nd cat and costs as much as CS ??? People will buy this exhaust because they have to have their exhaust tips exposed, also no MF exhaust for 2.5L ??? Corksport cat back and their axle back imo give the best bang for buck, especially if driving an AT, MT drivers you all are good regardless.
