Got a question about changing pipes on to my 09 superglide Iam sure it been asked before and i just didnt read back far enough... I am wanting to but on some simple slip on mufflers to replace the stock ones iam not lookin for anything super load just a nice sound. the dealership tryin to tell me I need to put in a race tuner and have it remapped lookin at $1200 worth of work by the time they are done. This month issue of American Iron they where puting short shots on a 2007 sporty and said that they were not installing the ECM calibration because most fuel injected bikes with o2 sensors will recalibrate themself after running for a few min. So have any of yall done this with out the tuner or remapping is it a bad idea to try and if so are there any slip on's out there that are close to the same as the stock ones but that will give me a better sound?
