Do i need to get anything else when i get this exhaust? I have a Fi200R EFI Controller Closed Loop already installed will that work for the tuning? Also does anyone know if i have to move my passenger pegs or any part on the bike to this exhaust installed?

Yes, that tuner would work with this system. The system comes with a relocation bracket for the passenger pegs.

By Andy
Answer Question

Will I have to remove the passenger foot pegs? I have a 2021 harley davidson softail slim

I have a 2021 harley davidson softail slim will I be able to put the this exhaust on my bike and still have the foot pegs for passenger?

From what I can see, you would need to remove passenger pegs in order to get this system to fit properly on that 2021 FLSL.

By Andy
Answer Question

is the fuel pack neccesary

It would definitely be a good idea to install a tuner such as the FuelPak with this system in order to have the bike running at it's best.

By Andy
Answer Question

Do they offer in chrome finish ?

Yes, after you choose your year/make/model, you will see the option to choose what finish you would like. Chrome should be an option that pops up.

By Andy
Answer Question

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

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

By Andy
Answer Question

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

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

By Andy
Answer Question

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

Getting a 2021 Fatboy 114 .

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

By Andy
Answer Question

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??

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

By Andy
Answer Question

Which ones are louder these or short shots?

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

By Andy
Answer Question

2008 fatboy. Can I still use the pillion footpegs

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
Answer Question

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

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
Answer Question

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

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

By Staff
Answer Question

Do they create enough back pressure???

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
Answer Question

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?

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

By Staff
Answer Question

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

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
Answer Question

Do I need to change my airfilter when changing pipes ?

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
Answer Question

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

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
Answer Question

Do these fit a 2018 Harley breakout 114

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
Answer Question

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

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
Answer Question

Do they come with mounting hardware and instructions

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
Answer Question

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

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
Answer Question

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

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.

By Staff
Answer Question

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

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
Answer Question

Will these fit an 07 sportster 1200 custom?

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.

Answer Question

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.

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
Answer Question

Does this kit come with mounting hardware?

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
Answer Question

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

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
Answer Question
