HMF question

Mudforce2010-08-11 10:22:03 +0000 #1
Okay I was supposed to get a Suppertrapp mudslinger but the guy I was supposed to get it from is being a dink.....So I need to know how loud the HMF really is. I have heard them before but seam really loud, but I have never heard one with the quiet core, are they a lot quieter? Any help would be great!!

They are about the same , check the sound clip thread for a comp.

Agreed. I have had both on my bike within the last 3months. They are very close to the same. The suppertrapp is a tad bit deeper in sound however that may vary from bike to bike.

The suppsrtrapp is a better built pipe imo. It is all welded construction, stainless steel, and you are allowed to repack it yourself. It is more in cost though.

In regard to the quiet core, it is noticeably quieter, however it also changes the tone. Most folks that i know don't like the sound with the core and don't use it. You should know that the mudslinger uses the same type core and that is how they achieve the near stock DB level that is advertised.

Also, not to Confuse the situation but the sound clips posted are not very accurate as far as DB levels go. Tone, maybe, but unless the pipe is obnoxiously loud it is a bit hard to tell. I bought the mudslinger because I thought I was getting a quieter pipe based on internet videos. It cost me $600 to learn this lesson that I am giving you for free, $250 + tax for the hmf and $350 + tax for the mudslinger give or take a few bucks.

Good luck with your decision.

BTW, before the " you could have bought a Muzzy for that price" comment is said. Keep it to yourself.

Espicially for Masher if he ever comes back. Let her eat!

Ya for me a Muzzy is out because up here in Canada I am looking at around $800. I can get a new HMF for $250. Does the Hmf with the quiet core sound more high pitched or just stupid? There are areas I ride were I need to keep it quiet, so I guess I would need the quiet core anyways. Thanx for the input guy's, I wish it was easier for me to get a pipe across the border but with no passport it sucks.

I think they sell for around $250 on various websites.

They don't sound stupid. It just has a lighter tone than without the core. Truthfully you shouldn't be overly worries about it. People over exagerate on how load they are. People's opinion on of loud vary. If the pipe has good packing and has not been sunk repeatedly, it isn't that loud.

Don't know what more to tell you.

Good Luck.

Not to sound like an a$$ here,but you guys are talking about slip on exhaust if I'm correct.There are minimum to no power gains with a slip on.The only thing you gain is noise.To have any power gains you have to run a full system with header.

I am not overly worried about power so much as the sound. I am jetted right now for my snorkels and gutted stock pipe but it loads up when idling and tends to pop at idle, when I get on the gas it is fine. But I want the pipe to make it run better.

Sound was the basic topic of discussion. Thanks for your input though.

Expect both pipes you are considering to lean the bike out more. They are through pipes with no chambers. The supertrapp is staged though. The header side internal diameter is about 3" and steps down to about 2 3/4" at about the center of the length of the pipe all the way to the end cap. My bike ran noticeably richer with the mudslinger than with the Utility. The Utility is same internal diameter the entire length of the pipe. The mudslinger would probably be closer your modified stock pipe. If you are running a high flow air filter, expect to re-jet with either pipe.

You may want to look into the swamp series. I have one taken apart at the present time, and it is a chambered exhaust pipe vs, straight thru pipe, and they are much quieter. Add the snorkel and you get the growl you are looking for.

I hate to turn this into a want to sell thread, however if my Swamp Series project pipe turns out as I hope, I will be selling my Supertrapp. It has one ride on it, and I built an exhaust snorkel for it. It will never see water on the inside. I just don't know when I will be done with my Swamp Series Mods, and be able to really test it out.

I sold my Utility to a forum member last week.

Good Luck

you mentioned the same thing in another thread, quit giving people false info. the only difference in the slip on and full system is the one front pipe. so your telling me that the front cylinder pipe gives you all the power in a exhaust system? please tell me all of us how that works because i would really like to know.
