Its all personal opinion.

 

I've heard Empire Exhausts bought all of Muzzy's stuff. Whether thats true or not, I don't know and if they did, I don't know if that means that they bought their patent?...Regardless, Empire exhausts videos sounded pretty good when I heard them on youtube. Just another option for you to think about.

 

Spawn - thanks for the tip. just talked with Empire and asked about Muzzy. Turns out they did "use" some of the Muzzy design, but they were a little cagey about coming out and saying they just plagiarized the thing, but I'm guessing there is more Muzzy in their design that they'll let on - which is fine by me! Plan on talking to the owner tomorrow to get more info.

 

HMF titan "swamp" series

HMF titan "swamp" series. quietest with a power increase. so people say. 94 db

 

Rjwe quiet cores

I put the quiet cores in. When you crank it up it's a little quieter, but once you start going it's significantly quieter. Does not hurt my ears anymore. I thought I was going to have to send the, back until I Put the quiets in. I'm glad I didn't send them back now.

 

I'm very happy w my Yoshi w spark arrester in..... no issues w wardens in NH and I believe they require 96 or 93 db or less

 

On the Yosh are you using any engine tune up other than the pipe? I have a 2016 1000Xxc and have been thinking about using the Yoshi muffler but have been concerned about a lean condition. Mine already seems real lean.

 

I’m running the yosh on my 16 outlander 1000r with a power commander 5. So far I’m using the supplied tune from dynojet for the pipe. Very happy with the setup

 

Yes I have a programmer.... you really should get one w any pipe even though can a man says it’s not needed with the Yoshi. My buddy has put over 600 miles on his 850renny with a Yoshi and no programmer and has had zero issues though

 

Agreed Put a tuner on it and I guarantee it will run smoother and cooler. I speak from thousands of miles of experience.:smilietwocents:

 

I have an almost new set of HMF duals if you're interested.

 

??

 

What color are they? Why are you getting ride of them? How much? Thanks

 

I had a performance hmf and it was way to loud, sold it for a muzzy in 2010 and was happy with it till it finally fell apart this past weekend. if you want quite look at how big the can is, usually the bigger it is the better it disperses the sound. the small diamiter cans will be louder. i think the only two options you have for being some what quite are the hmf quite titan or the straight line performance. i would add in rjwc but you have already tried them. I'm going with the straight line performance exhaust as its an open free flowing exhaust and some what quite compared to some others, the video linked looks like its put together really well too.

 

From my experience it would be better to just keep the stock muffler,less problems with having to tune bike because of the running lean issue. Unless you are a dedicated racer you will not tell or use the power difference,its mostly just a noise maker and you just irritate the guys you ride with.You will feel and be able to use the power you get from an aftermarket clutch(CVTECH best $500 you will spend) A loud pipe just means the guy with the best clutch setup wont have to look back to see how far you are behind, he just will be able to hear you back there.

 

The problem guys have with the aftermarket clutches is tuning them. They can be very tricky to dial in exactly for your machine. My aftermarket primary helped a ton, but I noticed a lot with my full exhaust (quiet muffler) and tune. Vforcejohn showed 10WHP gain with a full exhaust and tune, thats ALOT on an engine this size!

 

Ive always ran HMF on my 450 sport quads and held up good and producted good power. Just installed a HMF Titan QS on my renegade with programmer over the weekend. Ordered over black friday / cyber monday weekend and saved almost $170 combined.

 

Their website has option for either a single or duals for the renegade but only single for the outlander. I don't know why they don't make duals for outlander. I have dual muzzys and love the sound and performance from them. Hopefully Empire will make full dual for the outlander since they bought or copied Muzzy's design.

 

The whole benefit of the duals is to have twice as much muffler volume to cancel the noise! A single is typically louder unless it is restrictive.

 

I find it odd that Empire don't have duals, cause I have a brand new set, slip on only though. I've also seen his pipes on an Xmr outlander and xmr renegade.
He did have a full kit, bud but the head pipes he sent me wouldn't fit. So he refunded my money and said he wouldn't have another set until he could get a hold of another renegade and reset his jig.
So only slipons for now.
And since I'm coming from a completely stock exhaust to these dual slipons, I bet I'll see around a 4 to 5 horepower gain, maybe a pinch more.

 

Since starting this thread, I've enjoyed watching all the input and recommendations. I finally decided to go with a Straightline Performance pipe with their PC V fuel controller, and I couldn't be happier. While I loved the way the old dual canister pipes looked and sounded at idle, they made too much noise to ride for hrs at a time. Seat of the pants dyno isn't fair with the new set up, as I now also have the FC installed, but this combo rips, and is reasonable on the noise level - no matter how hard I'm hammering it. SLP's canister is certainly not small, which I'm sure contributes to it's great noise suppression, but it sure does pull at the bottom and all the way up - very happy with this set up. This combo, combines with the CVTech primary clutch is about all I think I'll do to the bike for now, but not ruling out head work and cams for the future.

Now it's time for some other incidentals, such as bumper, winch, etc. Any other suggestions on add ons I'm all ears. Thanks to all for your recommendations.

 

I've been following this thread for a while now, and I believe I am pretty well set on a Straightline Performance muffler as well for my machine. Make sure to post up again once you have some hours and miles on the combo, and let me know how you like it. Did SPI send a customized PCV tune made for their pipe, or did it come with more of a generic aftermarket exhaust tune?

How about some fuzzy dice on the handle bars & a bobble head or hula girl on the front rack.

I'm already using an inverted midget blow up doll for my beer cuzzie - does that count? :grin

 

Quite cores in a dual set up would have fixed your noise issue. Heck, even on the newer 16 and up Yamaha grizzlies a dual system makes quite a bit more power. And they only have a single exhaust port now vs the old 686 that had 2 ports.

 

I was running the quiet cores on the RJWC duals, and again at idle they sounded awesome, but the drone while running cannot be listened to without ear protection - could not hear that for hrs at a time. Still need to do a real ride with the new Straight Line performance canister, so I don't know how the noise level will be after the 2nd or 3rd hr of riding, but can confirm that power-wise with a short 15 min rip the power is equal to the RJWCs on top with improved bottom end.

 

The only one I find appealing looks-wise is the can am Yoshi.

The PCV from Straightline was customized specifically for their pipe, when I talked with them they emphasized over the phone multiple times that the PCV would provide a nice bump because it was programmed just for their pipe. Again, for the 15-20 min romp I did when I got it all together, I would agree. The low end definitely had more grunt, and the top end was screaming. I'm sure someone out there will get this and may disagree, and that's fine, but I'm very happy with the results and would recommend this combo with confidence to anyone - lol...and no I'm not paid by SLP or connected to them in any way, before some smartass asks.....:big-grin
