Hey whats goin on im new to the site, and was looking to get some feedback. I just bought a used 07 dyna street bob in Feb. that was bone stock. I just ordered and installed a set of Cycleshack Slip-On Turn Out Mufflers part # MTO-129, and was wondering with them being installed on the bike would i need to reflash the ecm now?? The bike does not seem to be running any different besides it having some kick *** sound for the price If anyone has any info/feedback/or opinion it would be appreciated.
Thanks

 

Congrats and welcome. If you are getting no back fire or decel pop you should be good to go. If you complete stage 1 with high flow you might want to look into the download. If you will do more mods to your engine then the purchase of a tunning device would be a good plan.

 

Like domenic said if you stay with only mufflers changed your already golden! If you can resist taking the next step your a saint! For the money it costs vs. the little bit of extra power you get is not worth it! IMO that is. But I sould talk ,I went and done the whole stage 1 thing. Even started with A/C muflers were next then download,then I read how I could get more power and torque from a power commander,damn if I didn't buy that too! At least now if i sell the bike I could keep the PCV and the download is still in there--- another 200$ LOL. Congrats , welcome, good luck ,and happy trails!

 

If you do a search on "download" or "stage one" or "ecm" or "power commander" or "fuelpak" etc, you should get about 10,000 threads. this topic has been done to death over the past 2 years.
