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.

Maybe you need more experience.
Some exhaust systems might be as you say, especially without a proper tune. But with a good exhaust, duals seem to be a better improvement over a single, and a good tune, which should be done by a Dyno tuner, there is most definitely power to be had. My 17 renegade made about 6hp and about 3tq, just with a dyno tune and PC5.
Will get my Empire Industries dual slip-on installed hopefully in April or May. And I expect at least another 3 to 5 horsepower gain from that.

You talking about Empire in Arizona that has duals because i was talking to him a couple months ago he didn't have duals available.

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.

On a stock motor, the duals (tuned) will only make 1-2 hp more than a Yosh single (tuned)....Get Torqed dyno'd multiple 1000's and this was his findings.

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.

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

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.

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

Wow, those RJWC'S must be crazy loud.
It will be a while still but I'll do a sound test once I get these Empire duals installed and tuned. Hopfully they won't be that loud!

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?

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
