If you can't get a pipe for that, you should just make a cone shaped tail pipe out of sheet metal, slash cut it, rivet it and paint it black. I sometimes wonder how much worse that would be than a Brocks muffler...I mean, the header is what is really important, right? Romes, didn't you make a "muffler" for your bike?

The goal here is to ditch that flow canister.Not necessarily the muffler.Unfortunately...that canister DOESN'T clamp on there at the 4 into 1 outlet area(it connects at the rear however with clamping)So a slip-on is okay.But I don't want a slip on.Full unrestricted system is what I want(and everyone else;).That canister also has a servo that closes down a butterfly when the rpms go up(noise).So unless a guy could cut that joining part ahead of the Can..then weld a straight midpipe into the muffler...it's a full system to replace.And nobody has one yet...except the H2R model..and it's just TOO loud for any street use.Doesn't appear Brock is gonna waste time designing one for the H2...sorry to hear...but someone will.
As an aside here..Don Guhl has already acquired TWO ECU's,the H2 and the H2R.He's already gone in...and has VERY good feelings about opening the H2's ECU up for max performance.The factory numbers are WAY low.He's correcting that as we speak;)The H2/H2R has over 800 maps in it for various particulars for the motor.Gonna take a bit of time to sort things out...but he feels totally able to be able to do it.Without harming any internals.The H2 is quite capable of handling very near H2R HP figures.Course...it isn't an H2R motor configuration,so it will have to be limited somewhat.I'm good with 250HP with this bike;)

I'd like to keep my license.I often leave early in the AM when riding season starts.Having a pipe like the H2R simply wouldn't work.I want to be able to actually hear the sc as I'm riding.You open this bike up with an H2R pipe on there...it's NOT like them starting it and revving the motor a few times.Like in those vids.Where I ride,it's mainly quiet and rural...though there are main hwys,as you know.Farmhouses and people are living just off the road and such...on those hwys.I don't need people calling the Sheriff saying"there's a LOUD Black bike running through here on his way to....".They will call.They like where they live for a reason;)I have to respect that.Besides...plugs or not,I want to keep my remaining ability to hear for a few years aheadLOL.
"People have no exhaust at all except headers sticking out of the side. It's loud but it's not the only bike that makes that much racket"...here it would be.Trust me.Last thing I need is for some redneck to decide he's 'gonna get that loud ass thing no matter what'..lots of guns here.People don't LIKE LOUD motors everywhere.There aren't but a couple of 'real loud bikes' here.Even the Harleys are toned down.The 'sportbike squids' may have LOUD exhausts..some do...but they make three or four runs at night down some of these roads...wheelying...and that's it.The Police are always looking to catch em.People here call this stuff in...they don't like it.I'd rather not be included on the hate list just for the sake of 'my bike sounds LOUD HooRahh..get used to it suckas".

I have to agree with Grn here, if you ride out in the country you have to consider the folks who live out there and their desire for peace and quiet. I left the exhaust on my new CBR1000RR completely stock for this reason, no sense in raising the ire of the locals with a loud exhaust, just MHO.

I mean, the header is what is really important, right?
Header Mid pipe is all the black magic. Forced induction rules a little different but the principle is the same.
coles notes
The additional psi of air pushed in on top of atmosphere renders talk of 2 hp gains a pointless discussion. Try think of it this way. If H2 guys Add Only one pound of boost, their gains will be 12 to 14 hp Through The Entire RPM Range.
Now That's A Statement.
This is a wow. And of course, no one ever only adds one lol. Talk of two hp in the Peek numbers on a naturally aspirated bike quickly become a meaningless conversation and not worth even a mention. Mute point as it were.
Now without stirring the pot with info I don't know for sure my thinking is the header is the same on both the H2 & H2R. Is it ?
That pipes unique shape and design at the head would have been a pain in the ASS to make or mass produce. That being said would they make two ? I have been looking for proof of this info and come up with ZIP.
If it were my Bike Slip-Ons with mid pipe only. Depending on quality of the Quality of the material used in the header maybe coat it. Too many unanswered questions at this point.
Romes, didn't you make a "muffler" for your bike?
Yes, Richard made for me from Busa designed pipe. My Gen 1 also had pipe and baffle.
Turbos are different in regards to how the sound will be. We have the turbocharger in the exhaust. This acts as a 2nd muffler. When additional muffler is added after the turbo we lose flow & hp but nothing to speak of if a large pipe is used.
This does not apply to supercharger. The H2 compressor pressurizes the air driven from the crank not the exhaust. That being said the bike has the potential to be louder. This way also has a parasitic loss. This loss # can be large on the bigger motors. The new Hell Cat takes a 78 hp hit to turn that charger. Yet still make 707 hp. My brain tells me I want that 78 back lol Always a trade off.
I have to agree with Grn here, if you ride out in the country you have to consider the folks who live out there and their desire for peace and quiet.
Especially if you do your runs in the same place over and over. Cops will be waiting sooner or later. I always add the muffler, my riding buddy steve runs the dump pipe and I ask him to shut bike off and coast before pulling into my place. Neighbors Give The Evil Eye. You Can almost here the sound of the phone dialing. Life.

The second effect more looks like I'd sneak a bernoulli effect there and speed the air in a sort of slow filling that header tip and then the smaller path being the bernoulli going down that tube if not a few inches and it is a diminishing taper off of that whole reason that chamber is letting the hot air fill that void first is a faster escape out the chamber.
And then I would assume the reversion is going to have an opposite and equal action.
the Quality of the material used in the header maybe coat it. Too many unanswered questions at this point.
My guess is the back-pressure meets right at that area and she pops there or burns right there at that spot. It was strange to see both of those pipes having the same sort of back 8" [each causing that] bluing. How do you answer that one?
That's how I look at the parts if no proof is coming forth.

Headers are the same on both bikes..45mm
"Here is the stock throttle-by-wire mapping for the H2R.
As you can see, the throttles are commanded to be fully open and they stay open, unlike the H2.
By the way, the H2 fuel maps are populated with comparable values to the H2R values. Read between the lines...
Enjoy!"..from a little birdie we all know here(no,he's not on this site).Couldn't copy his screenshot of the Map...one of 800;)

exhaust servo?
I know the subs are controlled by the fly by wire. No longer a main plate. You need to link that sub to your hand, not a lag-gear like the subs are with that actuator.
The only way to tell if those maps are equal between bikes is an 02 metered to it and that answers that.

"exhaust servo? "...yes...on the canister under there.Changes the flow rate for noise regulations.With the expertise of you know who that feature most likely as with the rest of the restrictions will be able to be 'diss'abled;)
That screenshots is only PART of the folders accessible.You did notice the folder..'throttle by wire'...and 'noise prevention';)
Not to mention...'limiters'.
"No longer a main plate".There are no subthrottle plates Hub.If that's what you're talking about.The velocity stacks aren't like the 14.With two sets of plates.Not sure what you mean...subplates.

"I noticed the commanded throttle opening difference as well. That's a common thing that I see with stock exhaust systems and racing exhaust systems. The stock system is likely more efficient in the lower revs than the racing version. Cams and cam timing have a similar effect, as well.
When I compare the fuel maps between H2 and H2R, the fuel values are greater in the H2 than the H2R in that same area, giving more validity to the notion that the H2 is more efficient in that area."...
Looks like it has 8 injectors.Nice;)
