With the stock front pipe and header there's a tolerable drone around 3k rpm. It's quiet as far as aftermarket catbacks go, and if you drive in a civilized manner you won't attract much attention. It is noticeably louder on cold starts during cam overlap, and the sound increases when you cane it.

I haven't put it on a dyno but it feels faster and I get more wheelspin in 2nd and 3rd, the charts I have seen show ~5hp increase on it's own. It will be more beneficial with other mods though.

Quality is spot on.
