Lemonade here.
Mate, I'm part of many forums, JDM, VAG and the like and this is BY FAR the most tolerant, friendly, chilled out, caring and helpful forum I've ever encountered. Yeah fair enough you find the thought of spending £1000 + on an exhaust ludicrous but others may differ. At the end of the day you get what you pay for.
From the outset you came across as a bit touchy and defensive. The members aren't here to take the mick. Everyone to their own and all that.
