Questions & Answers

  • Will these pipes fit a 2015 Yamaha Raider S

    By: Guest

    Yes, absolutely! The Vance & Hines Big Radius exhaust will fit the Yamaha Raider S for the 2015 model year.

  • How much H.P. does this pipe provide over a two pipe system?

    By: mark

    Without knowing exactly what bike it is that you have, its overall configuration or its state of tune - it's impossible to say what difference in power would present itself between the two types of exhausts. Furthermore, the two types of exhausts put their biggest gains in different places, and of course - those gains can only be fully realized with properly tuned fuel delivery.

    If you're interested in maximizing high-RPM power output, the two-into-two design is your best bet. For more low and mid-range power, the two-into-one design is king. This is due to the fact that each exhaust gas pulse from the opposing cylinder has a scavenging effect on the other cylinder's primary header, thereby pulling exhaust gases along more efficiently when the other cylinder fires. This simply isn't possible in a true two-into-two exhaust system.

    If you spend most of your time riding around town or cruising the highway, a two-into-one pipe is going to provide the biggest advantage for your needs. If you're interested in quarter mile times, then the two-into-two exhaust is your bag. But remember, in any case, you'll need to adjust fuel delivery to get the most possible benefit.

    For fuel-injected bikes, we recommend a Vance & Hines FP3 Fuelpak. If your bike is carbureted, check out our selection of Dynojet Carburetor Jet kits. Both items come with everything you need to get your bike set up for the best possible throttle response and engine power output.

  • Can you debaffle it?

    By: Raider s

    Yes, absolutely. All Harley-Davidson Big Radius two-into-one exhaust systems come with a removable baffle.

    By: Staff

  • will this hit my saddle bags on my 2004 heritage harley,and also,will it interfere with checking my trans fluid?

    By: LaPew

    So long as it's the stock Harley Heritage Softail's soft saddlebags you have on there, the exhaust won't come into contact with those saddlebags. As far as checking transmission fluid, again - it's not an issue. There won't be as much room to make the check, but there's plenty of clearance to do it without having to remove the exhaust system.

    By: Staff

  • will the exhaust system clear my rear pegs on my 2004 Heritage?

    By: mark

    On the 2004 Heritage Softail, the passenger peg on the right side is relocated with a provided bracket. It is lifted up out of the way of that exhaust pipe. Everything you need to fit the pipe to your bike is included in the kit.

    By: Staff

  • Are. There interchangeable baffles from quite to louder

    By: Mark

    The baffles that come with Vance & Hines Big Radius exhausts are removable only, there are no quiet or performance-type baffles available for these particular pipes. Once you pull the baffles out, the exhaust will become significantly louder.

    By: Staff

  • does this pipe have a deep sound ?

    By: shank

    Oh yes, certainly more of a rumble to them than the stock pipes they replace.

    By: Staff

  • can i alter the baffle to change sound ??

    By: shank

    You can certainly remove the baffle if you want to get more bark out of the pipe. It's held secure with a screw.

    By: Staff

  • Does the bike have to be tuned to run this exhaust or will it be fine without it.

    By: Guest

    Upon the installation of any full exhaust system, we always recommend that the bike be tuned to match. In this way, you can be assured the best possible engine power and throttle response. Most bikes, especially those that are carbureted, don't run the best when going from a completely stock exhaust system to that of an aftermarket design.

    If your bike is carbureted, check out the Dynojet Carburetor Jet kits we have, or if fuel-injected, have a look at the Vance & Hines FP3 fuel tuning system. Both kits come with everything you need to get the most out of your new exhaust system.

  • Can I leave the passenger pegs on my 2016 dynamics low rider?

    By: Guest

    No, in order to put this Vance & Hines 2016 Dyna Low Rider exhaust, you must remove the right-side passenger footpeg in order to complete the installation. Due to the exhaust's design, there's no way to fit the right passenger footpeg as there just isn't any room.

    By: Staff

  • Do I need to remove right pass peg on a 2006 low Rider and I have forward controls will it fit them

    By: Detroit

    Passenger peg removal is only required on 1986-1999 Dyna models. Later models can utilize the passenger peg relocation bracket that is provided with this kit. This exhaust fits Dyna models equipped with mids or forward controls.
