yeap.... any pipe change will require you to have the ecu setup to work with it. and you have a one piece pipe so you can't change the can either so you are kinda stuck. on the otherside, even with adding the pipe it doesn't make a huge amount of power over stock. plus if you do try and find a pipe, go with an aaen not dg, dg didn't make much more power on the old iron than stock, just more noise.
No sledding this season.... sold them both to pay for a wedding.
