Question Question about new OEM mufflers used lately...

WFT is up with all the bike makers all of a sudden switching to the single mufflers down below by the swing arm rather than how they were a year or two ago where they were up under the seat and usually there was two? Is there a logical reason for this? Or is it just a "cool factor" thing? Are these new modern single muffs better or something? Sure, they're obviously easier to get to and replace or whatever, but I never figured out why they ALL seem to have gone to those. Every bike dealer I browse in, any of the 4 jap brands, I notice almost all the new models have those smaller mufflers, down by the swingarm. Like this: (used this bike only as example. ALL makers started doing this with their mufflers.)

2007 Honda CBR1000RR (notice where muffler WAS):


2008 Honda CBR1000RR (notice where the muffler is NOW):


Well... WFT?

IMO, I like the old style better. I don't think I would ever want one of those smaller ones slung low. Hell, it makes the bike look like a 4x4 with lift kit. Gives a HUGE gap from tire to seat. And it only gives owners that much more of a reason to buy a fender eliminator or use their hacksaw. Maybe I'm trippin again but I don't really like it. I'm GUESSING it's to shift weight down to a lower point near the ground).

I know, I know, I ride a naked bike and sportbikes scare the sh*t out of me, so I should maybe stop worrying about bikes I don't even ride! Right Barton?

i'm not sure, but a thought would be a lower center of gravity w/o losing lean angle...

That was the only logical answer I could come up with. But what if we like the old ones? We (oh, sorry, THEY) need to now buy replacements to go up where they once were? Or did they even leave enough room?

All I know is the day the start doing this to naked bikes, I'll buy a freakin' moped!

The under tail ones made me think I was looking at the back of a cat with its tail up.

I like the undertail style personally.
My 919 doesn't emit that much heat, but I got a chance to take a Ducati 848 out for a demo ride last weekend & I felt quite a bit of heat from it.

The 1000rr had two holes. You have weird cats around your parts.

To each their own Bro. I like the idea of a 900rr header, but would still want my high mounted Satos. Low mount reminds me of cruisers.

I see it's pretty much a 50/50 toss-up on what we like and/or prefer. Myself, I like the undertail style.

But regardless of what we actually prefer personally, does anyone have any idea of WHO started the GP style and WHY? Was it based on public opinion or surveys, or did they just take it upon themselves to do it anyway even if we didn't like or want it?

Before they even started making undertail muffs, I always liked the headers with the muffs along the swingarm, like the old-school Kerker 4-into-1's. But the new style of muff just plain looks WIERD! Like stubby muffs (No, not the kind on a midget babe!) Yet so many manufacturers are switching to that style!

Let me guess....

It's cheaper! Yes? Anything to save a few production dollars without lowering the final cost of the bikes, which adds up to bigger profits for all.

I have no doubt some bikes with undertail muffs might get hot on the seat. Some may not. But then the ones that had the muffs beside the tail and not directly under it, like the 919 for example. Mine never get me hot. And I think a 919 would look downright GOOFY with that low-slung GP Style muffler on them. (Watch, Barton will rush out and buy one just to show me I'm wrong! That just sounds like something he would do!)


Oh, Brian, did you see my post where I ordered my new DC3 for the front? Yep! Will be in on Tuesday at my Honda dealer where I got my bike. Yee-Hah!

Less weight, lower CG, mass centralization. All part of making the bike go faster around the track. Magazine #'s sell bikes to the masses I guess. Just my opinion. The 919 is my first undertail bike, and I just have to say, there's something just really cool about two FUNCTIONING exhausts on a bike. Up high just shows them off. I think that's the point of a naked bike, you are showing everyone all the important parts of your bike, exhaust included. I like the GP style too though, so I'm really no help there. I think it's just about numbers for the manufacturer.

Ride Safe.

BTW, +1 on the 4 into 1 Kerker! Nothing beats those bad boys!

I've always likened them to a cow nose.

I used to love the undertail type like the 9'er till it stank me up and I pulled up to a yammie R6 with an arrow shorty gp style and man it really looked sweet and sounded pretty cool too!!

lol...i have a scooter, too! it's pretty much the best. note to self: with a low exhaust, you no longer need amendments to the swingarm for pipe clearance, less heat shielding required, more room for electrical gadgets and gizmos in the little tail, too!
