Man i just tried this mod and it is LOUDDDDD. And the car feels way slower for some reason. I don't know why but prior to trying it spool and throttle was right there, not with this it just doesn't seem right for some reason.
It was nice to hear what a cat back might sound like but I think it needs to come off for me :/
I can't imagine how loud it was outside the car. There were people like 100 - 200 yards away from me at a McDonalds that were staring at me. So it is probably way too "noticalble" for me.
Maybe I will take one side off and see if one side on reduces the noise by half.
