I bought an 02 F4i Craigslist special for $2k and it came with a scratched up D&D slip on. Even with ear plugs in this thing will make me deaf, not to mention it can probably be heard a couple miles away. I found one stock muffler for sale (for $600!) but considering it is usually the first part removed I was hoping someone could give me a better deal if they have one laying around.
