2015 Ultra Classic installed Rinehart 4" slip on's and swapped to the hi-flo baffle hoping for a little more "pronounced" or "loud but tuned" sound during idle, acceleration, and cruise. Although these mufflers have a very distinct and tuned sound they just don't say"hey, stand up and look what's running over here.' For 10 years I ran V&H slash cut duals that I think were 3.5 inch and they had that sound and feel. I'm not one to throw away baffles and hope for the best but what are we going to do with our "modern" exhaust? Is there anywhere to turn to for a true experts guidance??? Scott

 

Problem with how an exhaust sounds, it is very subjective..... experts can speak to performance because it's objective, when/if they speak to sound, it's just their interpretation/opinion... it's impossible to be an expert on something so subjective..

It's hard to compare sounds, without hearing an exhaust in person. I don't understand videos on a computer.... rarely have the exhausts sounded the same in person. Maybe similar, but never the same in my experience. You'll have to hear them in person, to really be able to judge.

Go to bike meets, hang out at dealer functions, and/or go on some charity rides.... sooner or later you will hear a bike and say, "That's it!!!". Find out what they are running and you're golden. To do anything else is a crap shoot, if you are looking for a certain sound above all other aspects of an exhaust....

 

what head pipe do you have?

OEM CAT muffles the sound a lot.


the Rineharts have two baffles, which one do you have installed, the loud or quiet?

other mods on bike?

 

The cats muffle your exhaust by at least 50% or more. When I put on my header, the sound went from very mild to almost to loud with the same Jack pot mufflers.

 

Ive got rinehart 4" with dresser duals on mine. It sounds pretty nasty but it doesnt have a cat in it either. And its got some other stuff done.

 

I put in the full-flow baffle. So I think that should be the louder one of the two. Extra $100

So I'm getting schooled here a bit. There's a cat converter in addition to the O2 sensors that is removed when you replace the head pipes? Do you then keep the O2 sensors or discard them and can it be flash tuned without the O2 sensors? Scott

 

 

 

Got it! I googled Harley and cat converters and found that Harley pre-2009/2010 put a cat of sorts in the right muffler only. Then in 2009/10 they started putting the cat in the "crossover" pipe connection. It's a tri-metal sort of cat versus a ceramic one in cars. That makes total sense why my 2005 ultra was so dramatically different when I only switched out only the mufflers. I presume that after market header pipes do not have the cat in them. I'm going to order some V&H true dual header pipe. Thanks to everyone!
