I just bought 4 recently and installed 3. The last one on the midpipe is too short so it looks like I'll either have to reuse the stock one or buy another straight from Kartboy. The resonator is tapping against my chassis so much without a hanger there and it's driving me nuts.

If anybody wants to trade a long one for a shorty or has a spare they want to sell, let me know! I'm located in San Jose.
