true everybody has their opinions, but you heard it in those vids the difference, i have some video i made today on the way home from the parking garage (I take the metro rail into the city) I have already cut them up into postable segments, but I am going to put them up from work tomorrow, my computer there is much faster when it comes to load things up. I did little things like start up inside the car and out, little revs inside and out, ALL THE REST ARE IN CABIN with windows down: cruising through the parking garage (definetely amplifies it), a semi accereration inside the garage, a 50% throttle into a turn, downshift into a turn, hard accel after turn, cruizing pass, windows down then up in one segment, silent to stock radio on at volume 22. I made some more later, but it started to rain so I couldn't really drive as hard as I wanted and I picked up my silencer to make some comparison video tomorrow. I am talking alot about it because I truely believe it is good. I researched alot of exhausts before the vibrant came out, then I jumped on the first group buy and was really worth it. I almost went with the Apex Dp and sp2 cat back, I already didn't like the corksport on two of my friends speeds. the video at the bottom is a friend's P5 with CS, i wish i could find the original to make it longer, so you really hear how ricey it gets. the backfiring actually sounds good from the vibrant, its more like a rumble popping, from the CS it tends to be more like a pop pop. i know that doesn't make sense. i guess I said a lot, just want to make sure you know everything you can before you buy regardless, i got a lot of info before i bought mine and i wouldnt trade it in for any other.
