I just installed a Muzzy 4 into 1 exhaust system and PCIII on my ’08 FJR and couldn’t be happier. The difference is remarkable. The engine is smoother across all rpm ranges and the performance increase is very apparent.

I was most apprehensive about the sound level of the Muzzy canister but it turns out I was worried over nothing. The sound level is great and the tone is very pleasant. I personally don’t like the whisper quietness of the stock system and I’m very happy with the change.

I would tell anyone who is contemplating the installation of the PCIII to do it.

Sounds like a nice upgrade. I've been considering a PCIII for a while mainly to tame my '07's twitchy throttle. I heard some nice exhausts at NAFO but most were too loud for my taste. Think I'll save my money for suspension upgrades instead.

On a side note - you might switch to Decaf coffee - that's one shaky, blurry picture! :sarcasm:

Ok I don't get it... 4 into 1? doesn't that restrict the flow?
A properly designed 4 into 1 system is more efficient because of the dynamics of the system. The pipe actually takes advantage of the momentum of the previous exhaust pulses to help scavenge the exhaust from other cylinders. I don’t know how much to attribute to the PCIII or the pipe, but there is a very noticeable difference from the stock configuration.

Sorry for the blurry picture. I was taking the pic in available light with a shutter time of close to ½ second. I’ll get a better one up soon.

Exhaust sound seems to be one of the more subjective aspects of this motorcycle experience. You’re talking to someone here who thought an open header on a Z1 Kawasaki was a beautiful sound.

Okay, someone help me understand this. First of all, I understand the dynamics of an "efficient" header, but what I absolutely cannot wrap my head around is the idea of maintaining that efficiency by having to push that exhaust gas through ONE muffler instead of two. I've seen thousands of examples of going from a single exhaust system to a dual exhaust system with headers on a car to increase performance, however, I've never once seen where someone added headers and maintained the single exhaust (on a V-8) or, as in this case, added headers and went from a dual exhaust to a single one. :blink: Seems counter-intuitive to me.

Can someone explain the dynamics/advantages behind a 4-into-1 exhaust??

It was :yahoo: I had a '74 Z1 with a Yosh open header and loved it...but I was 19 also :rolleyes:

Any pics of the other side that is now sans can? In my conceptualizing of an FJR with one can - I think I would like the bike better with two cans.

There are also thousands of examples of 4-1, 2-1, 2-1-2, for motorcycles, cars, racing etc. All racing applications I've seen combine, for nascar they run two 4-1 systems. You are not trying to pump more volume down a smaller pipe, the pistons fire at different intervals.

Each exhaust pulse creates pressure and a vacuum that slows things down as the exhaust egresses the pipe. Each pulse also creates a series of reflection waves back into the system that must be overcome by the next exhaust pulse. The 4-1 systems over comes the vacumm and minimizes the reflections and each pulse acts like a pump to pull the next exhaust pulse out. It gets more complicated with more cylinders; you need to consider firing order. Overlapping firings changes things, this is one reason that in racing applications V-8s don't run an 8-1 system. Search the internet, there are plenty of articles on exhaust performance.

Thanks, Bigtime. Again, I understand how a header works, I just don't understand once the exhaust gases reach the collector how it can be more efficient to route them out a single pipe than to route them out two (or more) of them....assuming that the single pipe isn't significantly larger, of course.

Don't mean to hijack the thread, Fergi. The bike...and the new pipe...looks great. I just never understood the logic behind going to a single exhaust on the FJR.

What the hell is wrong with you people? How much frigging power do you NEED?

I blow off a R6 riding 2 up on a stock 05 FJR.

Does anyone pay attention to the suggested weight limit on the FJR? When riding 2 up I'm over the liimit.

More power was not my primary reason for the PCIII although it's a very welcome side benefit. It’s the “driveability” that I’m so impressed with, smoother shifting, idle-off power. It feels like a different bike.

No No, hes fine, the house and bike were both moving in this shot!

Well let me try, If you take an airplane, and put it on a tread mill, then...................................

Boy, that looks great and you lost a fair amount of topside weight. Where did you get it from? I really liked the left side look and I now understand more fully a 4 into 1 system. Thanks to all
