Cobra True Duals Fishtail Exhaust System

You should have no problem installing this system on that 2000 FLSTC Heritage.

This system would have the proper O2 sensor threaded holes for the stock O2 sensors. No need for adapters unless you have gone to a different than stock size O2 sensor.

In the cas of the 1998 FLSTS fishtail exhaust system, there are no provisions for fitting oxygen sensors since the fuel-injected bikes from that time didn't have them either. Consequently, there's no need to purchase O2 sensor plugs to fit this exhaust to your bike.

Replacement tips can be sourced from Cobra USA directly. For this particular exhaust system they do not provide us with a replacement part number. We currently only have tips that fit the speedster/dragster systems available to us.

Yes, all required installation hardware is included with this exhaust system. You will, however, have to re-use some of the OEM exhaust mounting components to complete the installation. Given that you're only replacing the stock pipes, this won't be a problem for you. There is no need to purchase any additional hardware to get everything bolted up. And, the included instructions do an excellent job of explaining exactly how to go about everything. As for fuel delivery, you'll absolutely want to adjust the bike's tuning in order to get the most out of this exhaust. To do that, we cant' say enough good things about the Cobra Fi2000R fuel controller. As the Fi2000R is development in tandem with the exhaust by Cobra, you'll find configuring it to your bike's exact needs rather simple as there are only three knobs on the device to adjust. That, and the instructions for the tuner provide an excellent baseline from which to start your mapping profile.

Your best bet would be to continue with the tune you have for your current configuration, and then allowing the FP3's autotune function to do its magic. After a full tank of gas using the autotune feature, just flash over the recommended changes and you should be all set!

Yes, all Cobra True Duals Fishtail exhaust systems include a provision for fitting the oxygen sensors on Harley-Davidson motorcycles that are fitted as such from the factory. In this way, you needn't make any permanent modifications to your machine in order to fit this exhaust system.

For Cobra exhausts, we recommend a Cobra Fi2000R fuel tuner. The Fi2000R is developed specifically to work with Cobra exhausts and come with easy-to-follow instructions that explain exactly how to set up the device for your bike's specific needs. There's no smartphone interface either, just three dials on the tuner itself to get you down the road with the best possible throttle response and engine power output.

It really depends on what model year Softail it is that you have. For 1995 through 2006 model years, the coil stays in the stock location. For 2007+ model machines, yes - you will need to move the bracket in order to fit this exhaust. The good news is that this system includes a relocation bracket, along with easy-to-follow instructions so moving the coil is a simple, and clean operation. No custom wiring is required to relocate the stock coil.

Yes, everything you need is included in the box, though you will need to re-use some of the OEM exhaust hardware in order to complete the installation. So long as you have the stock exhaust on your bike, or you have the bolts and brackets associated with it on hand, you should have no problem fitting this system to your machine.
