So hadn't really seen or heard much about the SpeedSxS exhaust, ended up picking one up about a month ago, finally just got around to installing it. Definitely loud, but being as I pretty much am always wearing a helmet (CA law, or when Im running wide open in the NV dez I always have a helmet on) not to bad. Gets rid of that annoying tinny rattle off idle. Sounds super raspy and angry. Can tell Robby Gordon had a hand in designing it, just like his TT, its loud and will make a statement when running wide open through the dez. Haven't flashed the ECU yet, but feel like it has significantly more on the mid range and a bit more up top.
