Bassani Slash Cut Slip-On Exhaust

Generally, with slip-ons - there's not much else that needs to be done in terms of fuel delivery. Unless you spend most of your time riding up in the mountains, the OEM ECU has enough data available to compensate for the new exhaust. That said, however, you will find that since the catalytic converters are part of the headers, and not the mufflers, you may not get as much sound out of the mufflers as you want. If you want the type of sound that was on the Deuce (and it had a full exhaust), you may be a little disappointed with the sound that comes from these or any other slip-ons we sell. If that were the case, no problem really - you could keep the mufflers and add whichever headers you prefer as we have a couple different options to choose from. Of course, once you go with a full exhaust system - you will need to update fuel delivery with an FP3 fuel tuner since the ECU doesn't have enough adjustment to make up for that big of a change in fueling requirements. Installation and set up of that device is quick and easy - you only need a smart phone to configure it to your bike's needs and you're done.
