Not needing a tuner technically says they agree that they don't make power and need additional fuel. Sounds good by not needing to buy a tuner, but in the performance world its a kick in the nuts.
My 1,000 ran like complete $hit after I put my full Muzzy on it with no tuner. The tuner went on right after and OMG it was a huge improvement.

RJWC makes a nice product but noone has shown any dyno results from one that I have seen. Theres usually a real good reason for that.

If you just want looks and sound go for it. If you want to gain Power, keep reading and researching.

Deadman............. funny you mention this story about your Muzzy's, I have a story about that as well............ was coming back from Yerington Nevada with my Outlander Max 1000 and stopped and dropped my rig off at Muzzy for the full system with tuner in Bend Oregon (it was on the way back). When they called and said it was done my Cousin happened to be here from Alaska so I took him on the 3 hr drive South to Bend Oregon to pick it up from Muzzy. picked it up than out to the trails I went in Bend to check it out couldn't wait to try it........ and whole 3hr trip to Muzzy I was bragging on the power this quad had, and the additional I will have with the new system. Started it up and it sounded great but top speed was about 39 Miles and Hr, and it could barely burn out in sand, Muzzy turned my machine into a Lawn Mower. Called Muzzy and it turned out it was a bad tuner and all was well when they installed a new one, no problems since..........but it was sure a funny experience. Hope this does not happen with my new Renegade.....:th_smiliefrustrated

 

Yeah I'm not looking for more power, just looks and a better sounding exhaust than the fridge that can am installed. Thanks for the input. Cheers.

 

I would love to get one of these exhausts, but man are they every pricey. Was quoted $475us for single and $699us for dual slip-on.

 

$700 for a dual SLIP-ON?!?!

My full dual exhaust system from Muzzy was only $750 + tuner! Never heard the RJWC in person, and I know youtube videos don't do any exhaust justice, but comparing a muzzy video to an RJWC video, The Muzzy still sounds better....... and definitely makes power!

 

I know, its crazy for a slip on that gains no power. I can drill holes in my stock pipe and make it make noise for free.
Making power is what takes the research and tuning time, so i just don't get why these are so expensive.

who says they don't make more power?

 

I have them on all three of my gades. The fit and finish is just awesome. Now, as far as making power, I do not know. I never had anything dynoed. If anyone ever cuts open a Muzzy, RJWC, HMF or any other slip on, they are all pretty much the same inside. A straight pipe with holes and surrounded by packing. My best guess is that they all pretty much do the same thing. Give or take a little. I am not an expert, thats for sure. I did put tuners on mine and that helped. The first 800 I put it on it without a tuner ran a little hot, and the plugs were a bit white, so it was running lean. Yes, they are pricey, but you get an all stainless muffler, a billet aluminum end, with stainless packing and no rivets. I am happy with mine.

 

They look like a really nice exhaust and they pride themselves on not having to use a tuner. Anyone here using this?

As far as slip ons go, you are probably right. I doubt there is a huge difference between them. The full dual Muzzy exhaust makes considerably more hp over stock. The pipes are where the big difference is. I still can't believe anyone would pay almost as much as a full dual exhaust from Muzzy for an RJWC dual slip-on tho!

 

baffles me too……..

 

OH nice one......:th_smiliethumbsup:

 

Didn't VFORCEJOHN dyno the Muzzy full and slip on? I thought there was only 1-2 hp difference on a stock machine? So considerably more....no

 

I don't have exact number in front of me but Muzzy slip on with tuner made about 8 WHP gain. Full Muzzy and tuner made about 12 WHP gain! Thats impressive as heck! :th_smiliebanana2:

 

This is a dynotest from a Swedish atvpaper on three slipon @ Renegade1000 (87hp 93nm stock)
so most of the text for you guys i probably just jibberish but check the dynocharts!

No tuner used!!


Rjwc 2,37hp with quietcore 3.18hp without
Realpower 4.49hp
HMF Swamp 3.32hp

Looks like crankshaft HP, so those numbers will be higher in general just so people understand that before they get all excited over #'s.
I can't read the gains on the chart, its too small for my eyes. I can only zoom in zoo far n I still can't read it. Post the numbers if someone can zoom them in better.

 

Dyno from VForcejohn. Post #16

There was a discussion awhile back, not sure if it was on this forum or other. But the argument was that exhaust don't make horsepower. It just allows engine to flow free. So if your engine makes 80hp, that's all your gonna get. Now if you restrict the exhaust flow you may loose some HP and with aftermarket exhaust you can gain it back. Now there also the issue with back pressure which not sure some need and some don't need. This is question for some of the engine builders that understand this stuff.

I saw the video of VFJ where he had dyno slyder695 machine with and without the Muzzy and showed roughly 10hp gain. Wow pretty impressive. Now was this because slyder stock was extremely restricted or did Muzzy actually make that extra HP. I think he was restricted.

Then on another video slyder has a couple of races with 1000 scrambler. If my memory is correct there should only be a couple of HP difference between the 2 machines off the spec sheets. But since slyder has the muzzy on he should have more HP right. Slyder lost both runs by very marginal amount.

So my question is? Does aftermarket exhaust actually make HP or is it just smoke. I didn't notice any 10hp difference on my bike, maybe a couple HP.

 

The stock exhaust is usually choked off for noise and pollution reasons. The aftermarkets job is to create an exhaust system that extracts the maximum HP from the engine. They can either hit a home run and make power, or they can miss it and not make power. Theres more to it than just running a huge pipe that makes a bunch of noise.

Muzzy proved they make big power and are able to keep the noise down. Most pipes that make power typically are loud as hell and annoying. The hardest part in building a pipe is making power and keeping the noise under control. Anyone can slap a chunk of water pipe on it to make it flow, but that won't make max power. Its not as easy as it might look. Muzzy might make great power on these 1,000's, but then on a sport quad they might not make any power. My buddy and I had identical KTM 525 powered Polaris Outlaws and we took them to the same dyno on the same day. My quad had a HMF pipe, his had a Muzzy pipe. Mine made 2 more HP, so he put my HMF on his and re dyno'd and his made 2 more HP. He sold his Muzzy and bought a HMF. My point is, sometimes you nail it, and sometimes you don't!

 

Muzzy proved they make big power

That's what I'm looking for. Where you seeing the proof?

To me proof is having one machine and dyno it with stock, Muzzy, HMF and anything else. Ya, I see many dyno sheets comparing with before and after on stock vs aftermarket. I never see HMF vs Muzzy or other.

I've just come to the conclusion to buy what I think looks and sounds nice. I bought the Muzzy purely on sound and didn't want loud. But I would never say that I bought it because it gave me the most HP because I really don't know if that statement is true. If it did then I got a bonus. And don't you think all the pro racers out there would be running the same exhaust if this was true.

Not much HP gain.

 

Sponsors give them the pipes anyway….
