Hi, on my 2014 I have v&h true dual stage1 fp3 tuner with rush big louie 4" .Would 4.5 sound louder and deeper then what I have now? Thank you

I have a 2010 Street Glide, which came with a 2 into 1 exhaust system. I replaced the entire system with a Vance and Hines 2 into 1 Pro Pipe Chrome system. I'm wondering if one of these 4.5 mufflers would directly replace the V&H muffler, while still utilizing the V&H head pipes?

[@RCComponentsBowlingGreen]

We offer a 4.5" muffler for our 2 into 1 that uses a 2.5" inlet. Check the inlet size of your current muffler and see if it matches our 2.5" measurement.

Is that your RC head pipe? I'm thinking about switch'n to RC instead of Vance&Hines. I have a 2013 FLTRU and gonna start to build on it. I bought a set if SE255 cams for it and want a good pipe for torque with that bigger bike. Most riding will be done on the highway with 2 up most if the time. I'm gonna use the new ThunderMaxx wave computer and a stage 2 intake. I plan on head work and 10.5-1 compression later on.

James, yes the headers in this video are our RCX PowerMax Headers. These headers have shown to perform great on the larger cubic inch motors.

i've a 2016 limited low with v&h true dual stage1 fp3 tuner with v&h twin slash rounds and excaliber k&n filter. they pop like crazy when i'm coasting/slowing down. i cant stand it. and they're loud, high pitch.... i want a deeper tone with no popping lol, will the excalibur chrome work and not pop!?? and what will be the difference in 4.0& 4.5?

[@RCComponentsBowlingGreen]

Our 4.5" muffler will offer you the deepest tone and less chance of the decel pop. The 4.0" mufflers we offer are louder with more of a sharper exhaust note due to the smaller diameter baffle as compared to the larger baffle in our 4.5" muffler.

[@RideSkillfullycom]

Is it possible to describe how loud these are? maybe compared to stock? Or maybe with a db meter a prescribed distance from the tip? I do not want really loud mufflers. But I DO want mufflers with a deep thud/throb sound. Chasing exhaust for the right sound is expensive.

[@RCComponentsBowlingGreen]

Our RCX 4.5" mufflers have a 3 inch stepped baffle that creates a very low and deep exhaust note. You can still easily hear your radio at hwy speeds. When you want to twist the throttle up in the revs these mufflers sound like a hopped up v8 engine.

[@MrMud900]

would this same slip on fit my 2016 103 and my 2017 107 ? don't know which one to put it on. are the tubes the same size in the 103 & 107?

[@RCComponentsBowlingGreen]

The mufflers for the new 2017 107 motor are different in both length and inlet size compared to the 2016 103. We offer mufflers for both models. Here is a link to view our 2017 HD touring mufflers, kzbin.info/www/bejne/aH6woZ93erdrrJI

Curious if there has been any motor work to the bike in the video. Just making sure for how it would sound on my bike. How would these compare loudness wise with true dual head pipes on a stock 2015 Street Glide?

[@RCComponentsBowlingGreen]

No engine work was performed on this 2014 FLHXS in this video. The sound would be almost identical with a set of true dual headers.

[@gavinwhitaker4960]

recently fitted 4.5's to my 2015 glide which fuel pack would you recommend ?

[@RCComponentsBowlingGreen]

We offer our RCX Xcelerator Tuner. This is a plug and play tuner. You just plug it in and it automatically tunes itself. No downloads or dyno tuning required.

[@AJay27_IECA]

@@RCComponentsBowlingGreen Just received and installed my 4.5 slip ons dont seem to get the throat I'm hearing on here. Do I need to use a fuel pack-Also do I have to drop another $400+ for this one time update?

[@marvelous165]

Are the tips on the 4.5's replaceable?

[@carolinarider5237]

Yes

I bought these pipes for my 2017 Harley Ultra. They sound good but they are complete garbage. Very poorly made. The chrome started flaking and peeling after just a few months. Never, ever buy anything from RCX.
