Selling 4 used gintani tips purchased them with the intension to modify my Dinan exhaust with them, but unfortunately it doesn't look like it'll work. I'd like to get $200 for them (possibly with shipping depending on what the quote is). Located in Toronto otherwise. There's a rub mark on 1 of the tips and some marks on the bottom - but not noticeable when installed. The inlet size is 3 1/8" or 79.375MM. There's set screws on the bottom that can be used to tighten the tips onto the tubing.
