Muzzy Pipe, Anygood?

My friend's shop installed a Muzzy on a customers bike. Fit was awful for the headpipe section. It's all welded up as one unit (no spring loaded stuff) and the jig must have been off. Took a lot of work to get the pipes into the exhaust ports on the head.

On the dyno it performed in a very "average" manner even after adjusting the mixture with the Yosh box and trying a gutted airbox. 162 rear wheel, 2 less than the M4 system and 8 less than than the Akrapovic.

I have one on my 202 HP Busa. Need I say more? I will. I had an Ack on it at first and it sounded and looked like sh#t compared to the looks and sound of the Muzzy. Plus the Muzzy was $300 cheaper. The Ack makes one more HP on top whereas the Muzzy makes one more HP through the mid without remapping. Yes, the Muzzy headpipes are one but I had no trouble getting mine to fit whereas the Ack comes in 10 pieces with 20 springs holding it together. It was a no brainer between these two at least...
 
I have the Yoshi RS3, stainless and carbon duplex race pipe. I kept the stock mounts on and retained the pegs on the rear. Note, this is not the high mount pipe. Fit is excellent, no modifications needed for anything to make fit. Quality is excellent and the look is just bad *** . I wish it were a little louder though, it has a low deep rumble. Sounds like a "turbo" muffler on a muscle car. Loud at idle but fairly quiet on the road. I had a Muzzy on a ZX11. It sounded and ran good but after about 10k miles it rattled like a can of nuts and bolts and the packing was blown.
 
Been running the muzzy full ti with C/F oval off road can for several months. Love it. Fit is perfect, crafted like fine art, no sound like it on the market. Lee Shierts didnt buy the entire production run for nothing. Akro dyno's 1hp higher up top while muzzy 1 higher in the mid. Tossup. Muzzy is the only of the 2 available in full ti which means 1/2 the weight of a stainless system. For those wanting the absolute best, this is the one. 6lbs total system weight.
 
Oh yeah, forgot. After a month or so the headers and collecter turn blue/purple which matches my blue and adds a very exotic look.
 
I will let you know I have a Muzzy full ti with ti oval can coming should be here Monday.
 
zxalan, would I need to do any other mods to run a yoshi rs3 (to the fuel injection) or can I just add it to a stock bike and go?
 
I just installed the muzzy stainless with titanium oval canister on my bike Saturday.
Fit was excellent. It leaves alot more room between the oil cooler and header than the micron. My buddys micron rubbed a $100 hole in his oil cooler. It sounds great. Bike runs great and I am going to the dyno this week to see how it does. I was ecstatic when I found out the header was one piece..it makes for easier installation in my opinion.
 
to Buzzlat, I have not tried to run the RS3 without a remap on the injection but I would not find it to out of the ordinary if you installed and then just rode it. If you get hesitations or the pipe changes colors really quick or the spark plugs burn really clean or white, this may suggest a lean condition in which you would need to remap. I have the semi-airbox mod, short stacks, and a +5+5,0 map, all else is stock and my bike runs 146 mph in the quarter on a weak 1.83, 60'. I have the full race duplex with the race baffle, all of the brackets are the same and the pegs are still intact. The only way a race yoshi will affect the pegs or brackets is if you get the high mount pipe.
 
GSX1360R, with all due respect to everyone's tastes in pipes....I dont' see how you could say the Akrapovic looks/sounds like sh*t when compared to a Muzzy with any amount of objectivity. You had one, you chose to go with the Muzzy now. I wouldn't expect you to say anything otherwise. I've got other bikess in the garage that are Muzzy equipped and I'm pretty happy with them so this isn't some pro-Akrapovic advertisement. :)

The Akrapovics are all hand made...by one individual from start to finish..and it shows. Overall build quality and craftsmanship on the Akrapovic is higher than the Muzzy which I've also seen firsthand.

Spring loaded sections allow a lot easier fit on the bike too since you can slightly adjust where the pipes sit under the sump, into the collector and back out to the canister. It also makes for super easy/fast removal and re-installation time whenever the need arises.

The Muzzy (stainless headpipes) a customer brought in was decent looking but heavier than the stainless Akrapovic. Their welding jig was off slightly and getting it to fit was a real ***** . If you have a good one, you're good to go. If it's off a little too much....you're fubared for the most part.

Their ti canister has a great finish and doesn't look all that different from the Muzzy or M4 we've had. Oval ti canisters are oval ti canisters...different end caps, different decal/badge. It's not like you're comparing different carbon fiber weave patterns/colors or aluminum canisters that may have a brushed finish or mirror finish. They all have that same exact ti gray color.

Sound-wise...the Muzzy's louder for certain and has a more raspy/spitty tone to it. On my built ZRX it sounds great. Very nasty/evil and it shrieks when wound up to the point it makes the hair on your neck stand up. A very "in your face" pipe. For that bike, I love it. For the Busa, not what I want.

The Akrapovic has a deep bassy rumble to it and pretty much roars as redline approaches. More subtle and powerful to my ears. The Muzzy over time (give it 4000+ miles) will also get a lot louder and raspier to the point of being close to an open pipe in sound level. Of all the pipes I've equipped bikes with the Muzzy's have needed repacking far earlier than the Microns, Indigo's, Yoshimura's, etc. Just something else to consider if you're keeping the bike long term.

You're quoting the 1hp differnce between the two pipes. Were those your personal results or are you just quoting what's on Lee Shiert's site? I respect Lee very much and don't doubt that when he did his testing, those were the results. But our results were much different and the Akrapovic had the definite advantage throughout.

I agree the Ack is a product which has better build quality than the Muzzy but I have an "In your face motor" and the Ack doesn't quite cut it. The Muzzy looks and sounds more aggressive to me whereas the Ack has a low sweep to it with that dull canister and lacks the bark of the Muzzy at all rpms. The Ack is probably the best performing pipe for the Busa but it's not for me... Yes, my results were given by Lee but I was the one who told him about the success of the Muzzy pipe on a Busa in the first place. Three weeks later he tried his first pipe and now look: He's got more Muzzy pipes than Rob himself...
 
I guess it comes down to what you want.. I dont like the looks of the Akc. Pipes dull finish. (personal preference)I am going to call and it the race only RS-3 comes with out the high mount then that's the pipe i want. If not i am going with the muzzy pipe, Kawasaki still pops in my head when i mention his name...
 
Wait till you dyno, you'll be ready to puke. There's good reason why nobody runs yosh anymore. Akro or muzzy for those who know.
 
Know a guy who has Muzzy Ti pipe on '00 busa.
Headpipe fit is not very good. Very hard to get pipes centered up to fit the exhaust donuts. Tried twice and got exhaust leaks both times. Also the clamp type hanger just looks cheesy. On dyno with +5 +5 0 it made 161.2hp with BMC filter. Maybe some more tuning would help.
 
Has anyone tried a Sato pipe?

The are pricey (aboyt what an Akro runs). The dyno sheets that they sent me showed a 5.5hp increase up top and about a 9hp increase from 4000 to about 8000 rpm. It also held the power up top quite a bit longer.

These are japanese pipes so I would guess they are high quality.

Is the power that the manufacturer claims about in line with other pipes? They said that the dyno runs were done without remapping the EFI.

The street RS-3 keeps all the stock pegs and does not effect the blinker on that side. What if you just put a comp baffel in the street exhaust. Would that not be the same.Or i could rob the comp baffel off of my 90 GSXR, it doesn't see a lot of street use. Does Yosh sell comp Baffels seprately? Or just get the Micron. Tonight at the track i saw a 1300 with a Micron run a 6.19 in the 1/8. I thought that was pretty good. The Micron kinda looks cheap to me.
 
Well the race pipe is on the way.. I can always **** can it and get another. If i dont like it i'll get the muzzy or something else. So some one can get a deal on a Yosh RS-3 race if i dont like it. It pissed me off today barley made it to the house. cutting out bad. Almost sold it. Before i run it any more i need to make sure it has the correct cam chain Tensioner in it and give it a good once over. It's a 99 less than 2000 miles and i bought it from a 54 year old guy. I wonder if suzuki recordes the bikes that have been fixed...anyone know?
