I'm getting ready to pick up a new 2012 YZ450F tomorrow. I have had a few 450's before but seems like the pipes keep getting longer eah year. I can't stand how long the stock pipe is on the 2012. Who makes the shortest aftermarket slip on and will it require any remapping. I don't really want to spen the money on a full system. If you have any pics to show the pipes that woukd be helpful.
