I have really been thinking about installing a Harley muffler. That stock muffler with its iiiiittttyyy-bittty outlet can't be good on that engine, or can it? Being a musical guy, I would appreciate a good sound, but I would prefer not to have an ear-fatiguing muffler. I sometimes wear earplugs, but I don't want to feel like I have to wear them just because of the muffler. Wind noise is enough to worry about. How loud is the Harley muffler? I have listened to some of the recordings on YT. There is definitely a difference, but recordings don't say everything. What pipe diameter do I need to get? I have noticed that there is some variance in the length of these mufflers. Are the shorter ones louder? Is there any difference amongst the different mufflers.
Is the sound pleasant or a little much? How long can one listen to it without hearing fatigue? What are your experiences?

Also, is the big single more or less vulnerable to a restrictive exhaust compared to multi-cylinder engines? It would seem more vulnerable due to the sudden breathing requirement due to a single, large exhaust pulse, particularly at a relatively high engine speed for a 3.5 inch stroke. At highway speeds, the engine is turning about 4K RPM @ 60 mph, compared to an automotive engine of similar stroke length, this is insanely high. My Subaru has a stroke, I believe, of less than 3 inches, and cruises at only 2.5K @ 60 mph.

On the other hand, that one pulse has alot of time in that exhaust pipe to rest between pulses compared to a 4 cyl.

My thoughts are not quite mature on this subject, so some of this may be a little fuzzy.

No Monster for me, just some coffee. Maybe I'm just ADHD or something. I've been resting my crash-injured leg playing with this forum all day. I've been worried that I'm trying to take a cold or sore throat as well.

I would say that the greatest difference will be noticeable at interstate speeds/mid-high rpm under high throttle, where a restrictive system may run short on breath.

Will the savage run substantially cooler with the Harley muffler?

Yeah this bike is what it is, and nothing more.
You want to make it something it really isn't, then you might just look at another bike to satisfy your biking mindset.

The Harley clamp-on Dyna's  that I am sure Bot provided in that link work real well. It does not come off as a poser, just takes the tinny away.
Also, don't put too much stock in the tailpipe diameter, as the baffles are what restrict the flow more than the opening anyway..

Enfield muffler

Interesting on the Enfield muffler. I love Enfields, but there aren't very many around here, at least as far as dealers are concerned. I met a girl (a newb like me, even more so) riding a military green Enfield. She needed help starting it, but I didn't get that opportunity. I wish she would have let me kick start it . Those things are cool, hers had saddlebags almost like ammo cans, she had a front drum brake, which is Oh so cool on a 2008 . The funny thing is that it sounded substantially quieter than mine Maybe its just where I was on mine and she on hers.

Are you saying that the big single never gets a full charge of fresh air under normal conditions, or any conditions?
