Questions & Answers

  • Vance and Hines big radius exhaust, i would like to know the pipe size? 1 3/4 or 2 1/2

    By: louie

    Vance & Hines Big Radius exhausts for Harley-Davidson motorcycles have a 1-3/4" header diameter.

    By: Staff

  • Does this kit come with mounting hardware?

    By: Keith

    Yes, all required mounting hardware is included with the Vance & Hines Big Radius exhaust. Mind you, some of the OEM exhaust hardware may need to be re-used in order to complete the installation. So long as you have the stock exhaust on your bike, you should have no problem putting this on as there are no special fabrications required to make it fit properly. Everything you need is included in the box.

    By: Staff

  • I currently have the super radius system installed on my 2014 fxdl, if I switch to the big radius what modifications will I need? You picture the big radius exhaust with what appears to be forward foot controls installed is this necessary? I only have the mounting parts for the super radius is it interchangeable with the big radius? My main reason for the change is to replace the passenger foot peg that was removed to accommodate the super radius, you picture the big radius system with the passenger peg, I want to verify this and what if any other adjustments need to made.

    By: Jay

    So long as the Super Radius exhaust uses the stock header circlips and flanges, you won't need to make any modifications to your machine as it's currently configured in order to install the Big Radius exhaust. You'll just need to re-use those parts and also, the nuts that secure the headers to the cylinder headers when installing the Vance & Hines Big Radius exhaust. The exhaust itself is compatible on machines equipped with either, forward or mid-controls and everything you need is included in the box.

    By: Staff

  • Will these fit an 07 sportster 1200 custom?

    By: Sasquatch

    Yes, the Vance & Hines 2-into-2 exhaust indeed will fit the 2007 Sportster 1200 Custom! Simply select your make, model (XL1200C Sportster 1200 Custom) and year from our drop down fit guide that's to the right of the main image on our website and we'll get the correct exhaust on its way to you, fast.

  • Do u need to re tune the engen will there be Anny loss of tork

    By: Guest

    Any time you add an exhaust to your bike you should certainly tune it if you expect to get the most possible power out of the new Harley exhaust system. Otherwise, depending on the state of tune of your machine, yes - it may turn out that you lose power and torque at various power settings over the bike's rev range.

    To mitigate these problems, we recommend a Vance & Hines FP3 tuner if your bike is fuel-injected. If your bike has a carburetor, check out the Dynojet Carburetor Jet Kit. Both of these tools will allow you to get the best possible engine power and throttle response, all in one kit. Both items come with easy-to-follow instructions that clearly explain how to get the most power out of your bike.

    By: Staff

  • I have a 2012 fat boy lo , do you have these in chrome?

    By: Guest

    Yes, we do have a chrome Big Radius full exhaust system for the 2012 FLSTFB. Just choose your bike from the fit guide and select a chrome finish to get the Softail exhaust that you want.

  • Installing on 2007 FLHTCH, Does this exhaust system have sensor ports? and removeable baffles?

    By: AL

    For the 2007 FLHTCH, this exhaust does indeed have a provision for installing the OEM oxygen sensors. As for the baffles, they are indeed removable. Each baffle is secured in place with a single screw.

    By: Staff

  • How hard is it to remove baffles on this exhaust system ?

    By: Anthony

    Removing the baffles isn't particularly hard, especially with the exhaust is brand new. They're both secured with screws, so it only takes a few minutes to pull them out. That story, however, changes pretty quickly once you've put a few miles on the exhaust as the dissimilar metals between the baffles's screws and the muffler bodies tends to weld the two parts together over time.

    SO! To prevent that from becoming a problem, when you first go to mount this exhaust, take a few minutes to pull the baffles' screws out and put some anti-seize on the threads. This way, should you decide sometime in the future that you want to remove the baffles, the screws won't be welded into the mufflers. So long as you take that simple step, you won't have any problems removing the baffles later on.

    By: Staff

  • I have a 18 Harley low rider FXLR. Will I need to move the rear passenger peg at all or will it be able to stay in the same place?

    By: Brian

    No, there's no need to move the passenger peg in order to fit this exhaust to the FXLR Low Rider.

    By: Staff

  • Do they create enough back pressure???

    By: Cochino

    Yes, all Vance & Hines exhausts that we sell, including the Big Radius, provide enough back pressure for the engine to run correctly. Each system is designed with a set of baffles that are engineered to deliver the correct exhaust flow in all riding conditions.

    By: Staff

  • Do u need to install a map to run this exhaust?

    By: James

    Yes, we always recommend that fuel delivery be updated when installing a new exhaust system, especially if your bike is of a completely stock configuration.

    For all Vance & Hines exhausts, we recommend a Vance & Hines FP3 Fuelpak to do the job.

    It's simple to use (really!) and can easily be configured to work with all Vance & Hines exhaust systems, including the Big Radius.

    By: Staff

  • 2008 fatboy. Can I still use the pillion footpegs

    By: William T.

    Yes, you can still use the pillion pegs on your machine with this particular exhaust. There's no need to remove the passenger footpegs in order to install this exhaust on the 2008 Fat Boy.

    By: Staff

  • Do these pipes have the oxygen sensor ports for the 2011 street glide ??

    By: Guest

    Yes, the Vance & Hines Big Radius exhaust for the 20114 Harley Street Glide does come with oxygen sensor ports. Simply remove those oxygen sensors from the stock exhaust and re-install them on the new Vance & Hines exhaust system.

    By: Staff

  • Do these fit a 2018 Harley breakout 114

    By: Robert

    Sure will, just be sure to choose a 2018 FXBRS Softail Breakout 114 from the dropdown menu and we will get them on their way.

    By: Staff

  • Do they come with mounting hardware and instructions

    By: Guest

    All Vance & Hines exhaust components are shipped with a complete set of easy-to-follow instructions and all required mounting hardware. In some cases, you may need to re-use some of the OEM exhaust mounting brackets and/or hardware. So long as you have the stock exhaust on your bike, or at least, all of the stock exhaust components available to you, there will be no problem fitting this exhaust to your bike.

    By: Staff

  • Vance and hines states pn 21946 relocation bracket is required for 2018 114 heritage is it included

    By: b miller

    The bracket is not included. It allows use of OEM saddlebags on 2018-2019 Harley Sport Glide Heritage Classic Softail when using Vance and Hines full exhaust systems. You can find that bracket in our store by searching "Vance & Hines Saddlebag Support Bracket" in our store search bar.

    By: Staff

  • I have the 2018 breakout and i am told i have to have a bracket for the back passenger footpeg can you tell me what i actually need for the right side and left??

    By: eric

    Yes, this system actually comes with the relocation brackets and clearly state in the included installation instructions how to properly install.

    By: Andy

  • Do I need to change my airfilter when changing pipes ?

    By: Leon

    Changing the air filter is not a requirement but will help benefit the motorcycle when paired with the appropriate jet kit or fuel tuner for maximum performance from your motorcycle and this new freer flowing exhaust system.

    By: Staff

  • If I'm only doing the exhaust will I need to tune it ?

    Getting a 2021 Fatboy 114 .

    By: Raffe

    For a full system it would be recommended to have it tuned or install a fuel tuner.

    By: Andy

  • Which ones are louder these or short shots?

    By: Mike

    My personal opinion is that the Big Radius pipes are louder.

    By: Andy

  • Do they affect the riders floor boards on a 2018 road king

    By: D Q

    For the exhaust, there's no need to modify the OEM floorboards when installing it on a 2018 Road King.

    By: Staff

  • have 2018 fatboy 114 will the big radius interfere with passenger pegs at all

    By: slickhd

    So far as we're aware, this exhaust system doesn't interfere with the passenger footrest on the 2018 Fat Boy. You can still use the right-side peg without issue.

    About the only time we run into issues with this exhaust/bike combination is if you're using saddlebags on the bike. The exhaust us too big to work with saddlebags.

    Other than that, the pipes fit perfectly!

    By: Staff

  • why will the big radius 2 into 2 exhaust system with black heat shields fit my wide gilde 2005

    By: pete

    After checking with Vance & Hines, they only produce this system in chrome for that 2005 FXDWG and not a black version.

    By: Andy

  • Will these fit on a 2019 softail streetbob without Removing rear foot pegs

    By: Guest

    You would need to remove the passenger peg in order to allow fitment of this exhaust system on that 2019 FXBB.

    By: Andy
