The Power Duals have a crossover/power chamber design (2-1-2). This allows for exhaust scavenging, leading to better efficiency and performance. The Dresser Duals are two completely separate pipes (2-2) and will give you a louder, sharper exhaust note. The Dresser Duals will not increase low-end performance like the Power Duals when compared to one another.
This depends on the motorcycle and where the catalytic converter is located. If you have a Harley-Davidson touring bike, the catalyst is in the head pipe. Therefore, if you only change the mufflers, you will not need to tune the bike. However, if you change the complete exhaust system, including the head pipes, you will need a tuner and a high flow air intake is highly recommended to accommodate the increased airflow exiting the combustion chamber. Other motorcycles vary model to model, and it is recommended you contact V&H for model-specific clarifications.
Yes, so long as we still make the system in question.
Twin cam exhausts, with a spot-welded exhaust ring, have flat gaskets included which is recommended and different than the stock tapered gasket. Twin cam and Milwaukee 8 full exhaust systems, with an “A” formed end, utilize the stock factory gaskets. Milwaukee 8 Softail slip-ons do not require the stock muffler gaskets to be used on installation, as our slip-ons are fitted to the stock header diameter.
Vance & Hines® exhaust systems are made to fit a specific model and year range. If your bike is within the model and year range, then the exhaust will fit your bike. Unfortunately, exhaust from a certain model will not fit a different model. i.e. Softail pipes will fit Softails only and won’t fit on a Dyna, Sportster, Street, V-Rod, or Touring models. The same goes for Sportster, Dyna, Touring, V-Rod, and Street models.
All Vance & Hines® exhaust, intakes, Fuelpaks, and accessories are made in the U.S.A.
The easiest way to remove the baffle is to remove the screws and use a slide hammer with a hook at the end of it. Insert the slide hammer hook onto the end of the baffle, and remove it.
After the baffle has been removed you will insert the new baffle all the way inside, it will be a tight fit, and use the baffle retaining screws to secure the baffle within the header.
Yes, the plastic wrap is left on the baffle as it will burn off once the mufflers get up to operating temperature.
As long as your motorcycle is tuned appropriately, you can safely remove the baffles in most cases. However, V&H does not recommend doing so. Removing the baffles will cause a severe loss in low to mid-range performance, and in many cases cause unwanted issues like popping, hesitation, and surging.
Yes, we do offer replacement baffles for the majority of our exhaust systems. Search for your exhaust on our website and look for the standard, competition, quiet, and super quiet baffles that fit your application.
All of maps are made on a dyno and verified on the road with the engine/pipe combination listed. Every map goes through a full tuning process and is reviewed by calibration engineers.
First, verify that your FP3 app is up to date through either the Apple App Store or Google Play Store. Next, connect to your bike and FP3. Verify that the firmware is up to date by going to 'Customer Support' and pressing 'Check for Firmware Update'. Install firmware update if available. If still unable to flash, go to 'Customer Support' and press 'Upload ECU Content', then try flashing again.
Before making additional changes for camshaft(s) and/or engine modifications, you must first flash a base map onto the bike. Then, go to 'View/Edit Maps' and select the map you want to edit. Under the 'Air and Fuel' section you will find 'Camshafts'. Under the 'General' section you will find other critical tables such as displacement, injector size, and rev limit.
Yes, the U0100 trouble code is a historical code that occurs when flashing the ECM. You may have one or several after flashing, which is completely normal and will not trigger a check engine light. You can periodically clear these codes out through the FP3 app if they occur.
Vance & Hines offers an extensive one year warranty on the Fuelpak FP3.
To Autotune your map, you must first flash a base map onto the bike. Then, select Autotune from the main menu and select 'Quick Setup'. Next, choose the map slot you would like to base the Autotune off of. This will initialize the Autotune process by flashing the bike. Now, go out and ride. The more varied types of riding you can do (stop and go, steady state, uphill, downhill, low rpm, high rpm, low and high throttle angles, etc.) the better. We recommend 3 sessions, each approx. 30-60 minutes in length. 'Apply' the data after the 1st and 2nd session, 'Finish' the Autotune after the 3rd session. During Autotune you may experience issues such as poor cold start, poor throttle response, and general ride quality issues. These will resolve once you 'Finish' Autotune and the map is re-optimized.
Yes, once a Fuelpak FP3 has been used to flash a bike it is permanently married to that ECM. You can use the same Fuelpak FP3 on other bikes to read/clear trouble codes and view live sensor data, but will not be able to flash a different bike.
The Fuelpak FP3 may be removed from the motorcycle once the map has been flashed to the ECM. For Live Sensor Data and Diagnostic Code reading or any other map editing or viewing the Fuelpak FP3 must be plugged in.
Vance & Hines offers an extensive 1 year warranty on the Fuelpak PRO.
Fuelpak Pro utilizes two included Bosch Wideband sensors that can be installed into any exhaust with 18mm sensor bungs. The sensors take live data while performing a tuning session, and the Fuelpak Pro module monitors and maintains optimal wideband temperature ranges, sending data to our best selling Fuelpak FP3. The Fuelpak FP3 app will serve as your main user interface for the mapping procedures outlined in out Installation and Tuning Guide.
The Fuelpak Pro is intended to serve as a tool for dyno technicians, and is not required to stay with the motorcycle once tuned, not does it marry itself to any one vehicle. The Fuelpak Pro can be used again and again on multiple vehicles, but each vehicle will require its own Fuelpak FP3 that will marry itself to the vehicle, and be left on the motorcycle for the customer after the bike has been mapped.
Vance & Hines warranty is one year from the purchase date, and we will need to see pictures and proof of purchase in order to process an RMA.
