I have looked and looked at TONS of posts.
I have 1 simple question.

What pipe produces the best power WITH the Spark arrestor AND optional quiet core?
Is there such a thing???
I don't want to pi$$ people by being WAY loud, I just want it to sound GOOD, not burn the forest down and put out the ponies!!

 

Don't get the HMF if sound is a concern. I think it has an amplifier instead of a muffler. I went blind, deaf, and dumb on my last ride and my pancreas hurts like he77. Power is good though [img]i/expressions/face-icon-small-smile.gif[/img]

 

Try the FMF Power Core 4. It has the spark arrester, Great power, fits well and tucks up nice and high, Quality is awesome, and it is not very loud compared to alot of atv's i've heard.

 

I first tried the FMF, then sent it back for being too loud. But I think it may have been the best overall.
I have the HMF with spark arrestor and quiet core, which I modified. It is okay, a little loud, performance is okay, fit and finish are great, but I think the FMF was a little quieter, with a little more low end. It is a close call though, And the HMF quiet core is way too restrictive, felt like a stock exhaust till I doubled it in size and flow. By contrast, the HMF on a Raptor is awesome, but then anything but the stock exhaust is awesome on a Raptor........

 

Hey JMAC650...

How loud is "not very loud"? I ride mostly at the Oregon dunes and they're very strict about sound levels (93db is the limit). Do you think your pipe would pass? Does it require a mid-pipe?

MudStud asks a great question. I'm in the market for a slip-on for my Bomb and I've read lots of related posts on this forum, but I have yet to hear a definitive answer. I've heard great things about the Yoshi pipe as far as power, fit & finish, and quality, but lots of confusion regarding how loud it is. I've heard similar great things about the MBRP pipe, but nothing about noise. What about the Big Gun? Pro Circuit? CT Racing? White Bros.? I'm sure every pipe available for the DS650 is represented among the regular participants on this forum. What do you guys have to say about your experiences? Thanks in advance for the info![img]i/expressions/face-icon-small-wink.gif[/img]

 

FMF Powecore 4 is a nice slip-on! Not too loud, but good overall power, especially the low end. I know where someone could get a good deal on slighty used one![img]i/expressions/face-icon-small-wink.gif[/img]

 

where? Is it a NEW pipe version or old pipe version?

 

Do you have an email address? I can email you the info or you can turn on private messages in your profile.
