He has a opinion of what he likes and doesn't like... How is that trolling?
Just because he doesn't like it and has stated over and over again that he doesn't like it he's a troll because he doesn't agree with the majority of the thread?
For that matter I actually agree with him when the CSS muffler is paired with a aftermarket downpipe. I want something that's subtle with a aftermarket downpipe and doesn't drone on the highway. When I go WOT on the back roads I would like a bit more of a roar vs scream. Very few exhausts mesh with the sound that I'm going for.
That's not what makes him a troll.
Through this thread he has been straight up irritating and trying to get a response.
He then became intentionally rude/crude to one member to draw a response, which is when members labeled him a troll.
It's clear from his posts that he isn't interested in the muffler anymore and he told another member in here that if he heard the exhaust in person he would laugh at the Members face.
It's one thing not to like something but it's another to say that.
It's so silly and ridiculous that he would say that, much like someone would say when they are just trying to get a rise out of someone.
In real life I doubt he would be so rude and bold, however this is the Internet.
