Insane new exhaust by HPE for R1200S(they make two types)

Sorry Robert..........it does not make 123 HP at the rear wheel with the exhaust system in question. In your heart or hearts........you know that. Anything near 115 to 118 at the rear wheel...........using a exhaust system only, no chip or other mod, is about it........and would be(115 to 118) considered very good and worth the money. 123 simply is not going to happen. Thoughts...??

Let's say stock would make 110 RWHP. Is a 10HP gain that far fetched? For me, it's definitely larger than I would expect, but I wouldn't consider myself qualified to judge.

However, I have read in Superbike(shocking mag btw) magazine in an exhaust comparison that an Arata exhaust gave 11HP on a 2005 CBR600RR. I'm sure the R1200S is much more restricted than a stock 600RR, so I don't find HPE's claims to be unbelievable.

Thoughts?

Sick is right, I think I taste some of my breakfast coming back up... a three-port exhaust on a 2-cylinder bike?!?

Good thing I opted for pop-tarts this morning instead of an omelette.

All I could think about is this must be a mistake, these should be on the Triumph Sprint ST with it's triple thing going.

I like the twin thing my 11S has going on...

Just being socratic and you responded as an academic in a dialectic fashion.

My post had a hidden agenda, "Do we believe everything just because it is"?

Not!

Good to have fun with you Doc!

Always great to hear from you Robert, and to read your posts as well. Lets all hope that the exhaust makers keep on trying till they get it right. The BOS still seems to be the HP leader in real life..........but my gosh....the thing sticks out the back like a rooster tail. Still.........wish I could get hold of their top of the line unit to compare with the stock bike exhaust in terms of top speed. I have the 2.62 now and can't wait to see what a bone stock R12S will run top end............and then be able to see what the same bike will run with just the BOS added to the mix.

Any idea Robert as to when we might see some of the trick BOS top of the line units?

No doubt, it makes no sense, but it does llook nice...

I like how the pipes follow the curves of the tail light...

Who makes that hugger?

...Bob ; every carbon part you see on that yellow bike is Ilmberger stuff (Julius Ilmberger is also the HPE exhaust importer)...
...over here the hugger is about 240 Euros, and comes with a few special bolts to mount it…
...the quality is very good ; the looks a bit doubtful though…
…somehow the 11 looked better with a hugger than the 12 does… (IMO)

…I will give mine a different color ; I think I’ll go for the same black egg-gloss finish as on the drive shaft unit…

[Bob Hancock]

I think it looks great, Ron. Bubba found one on ebay so I may get that. It's $299 which would jive with 240 euros I guess. I asked the seller if it came with the mounting hardware. Does it mount the same way as the R11S?

[RoLoo]

…nope ; on the 1100 the Ilmberger hugger uses the mounting holes the rear brake caliper uses, so the aluminum strip laminated in the carbon fiber hugger is visible on the outside of the caliper. On the 1200 you have remove the rear wheel, and with a few tiny bolts (same bolts BMW uses, but without the standard washers) you have to mount the hugger in such a way, that it fits just between the rear wheel rotor, and the drive shaft housing…

So they supply slightly longer bolts to bolt rear wheel and hugger onto bike. Hmmm. Looking at it, are you happy with this arrangement? I'm not an engineer, but this worries the gears in my head. Thanks.
EDIT: Ron. I got a response from the seller and it appears that you remove the three bolts to the drive unit, remove washers and install the hugger. Right? I have one of these units on my R11S and it's been doing well. The aluminum part is solid, so hope this unit is built well too.

More importantly: Will this Ilmberger hugger design snap off like their R1100S hugger design did?

...Jeff, Bob, I posted the answers in a new thread (a hugger thread... ) : just do the click thing here...

[r1200S]

So i still never got a price and availability info, anybody know if or when this system (The nice chrome one on page 1 with the yellow r12s) will be available? I WANT ONE!!!!

[Michael Derby]

I'm with r1200s - I want one too - any info anyone could share???

[Skoeter]

Hi all,

Exhaust systems on bikes are actually a very grey area. Everyone has his own opinion about gains made. When looking at the graphs supplied by these manufacturers it is very difficult to compare actual results. All use different correction factors and other fudge factors in order to have nice looking graphs, not to mention the smoothing of the curves.

Are there any sources that can be trusted that can supply realistic results that can be compared in order to make an informed decision.

Cheers

Here's a tuned R1200S with the HPE exhaust, HPE streetheaders with catalyser and a rapid bike controller.
It gains almost 6hp (118hp at the rear wheel compared to 112)
They also have the headers in titanium for all weight freaks (no weights are shown..)
