I just got my XSR900 about a month ago! I live in Los Angeles California, so emission laws are a little bit strict. I picked up an Akra carbon full race exhaust system thinking that that I wouldn't need any tuning done, however, after reading some of the threads on here, it would appear that I should get some kind of tuning done. I also read that the Akra Titanium full race exhaust doesn't need any kind of tuning. I chose the carbon because of the better performance it gives for a much lower price, but since I now realize that I have to pay for some kind of tuning, (I don't know what kind I need exactly-- still learning) I was wondering if any of you California/Los Angeles riders know where I can get this done? I was also wondering how, if at all, would returning the bike affect warranty. Finally for the more general XSR forum, do you guys think it would look better and be easier for me to just trade it the Carbon for the Titanium Akra? I will more than likely try removing the baffles on the titanium Akra if the sound still doesn't satisfy my liking (I'm used to my Monster's deep/loud rumble) but would that affect mapping too? would I need to perform any re-tuning if do that too? I wouldn't remove the baffle from the carbon one because I've heard some audio files for all three of Akra's exhaust systems and the Carbon akra sounds quite pleasing while the titanium ones seem close, but, again, not quite to my liking. Thanks in advance for those of you who repond I'm really happy to be a part of this forum! Cheers!
