Exhaust question
So...I have been holding off on buying an exhaust for my 10R and the 14 (when it comes in). I was always of the belief that the bike loses power and TQ at low end when moving away from the factory exhaust setup...as this is how every bike in the past has behaved before when I chaged the exhaust. Now I'm thinking its time to make the jump...I'll start with the 10R and if that works well, do the 14 whenever I get the damn bike.
Money is not the deciding factor in making the choice, and I've decided the only way to go is to a full system so I get power and TQ at bottom end.
I want power, 4-1 and light weight...I was looking at the Brock setup or the Muzzy...prefer to go stainless, but if weight is substantially lower on CF, might go that way. I need some advice, from those who have already installed something like this before on the 04-05 10R. I want to know from your experience in the street, what I can expect. I dont want to add a PCIIR or do any airbox mod's save maybe a K&N filter ...

Torque - just torque - give me torque at low rpm
Hmmmm. 98 Nm @ 2000 rpm doesn't sound that bad
What happens if I bore it out to 1532 using Muzzy's kit
and then get the compression higher!

I'd steer away from CF cans.
Ti is much more forgiving.
CF does not handle heat so well, and will tear at the bolt holes / rivets, if you let the muffler packing get worn out. The muffler packing provides quite a bit of structuraal integrity when tight.( read : FRESH).

About the only full system I'm aware of with which a power confounder isn't a pretty much a necessity to maintain ridability is the Akrapovic.
Personally, I wouldn't buy a Muzzy, but only because I'm still bitter about the horrid looking, ill-made 'thing' I bought for my old ZX11. Besides it never fitting properly and burning my bodywork the damn thing looked like something that came out of a gradeschool shop class. When I drove over to Bend to show the folks at Muzzy they just shrugged it off.
That did it for me with Muzzy. YMMV.
I'd go with a nice TiForce or Akrapovic. They'll come along...

Got a PM from someone who had suggested the Acropovic full system and I checked it out, but even on their site, they indicate that under 5K, the power curve goes opposite to the stock setup, so there is substantial loss of HP and TQ under 5K, which is what I'm trying to avoid. Gains were about 11 RWHP at peak and similar type of gain on TQ, but the loss under 5K bugs me still...I dont launch at 5K when riding street...if it were under3K I could deal with that, but 5K...hmmmmm, not sure I want to go that route.

I want the opposite!
I want more power and torque below 5K than above
It doesn't hurt to get it more above
but surely my main concern is to get more at low speed
Why?
a) I like cruising and most of the time I ride below 5K
b) the bike has - like RR - "enough power" and then some more
c) While on a traffic jam I have to constantly slip the clutch
which I don't like - with more torque IO can just idle ahead
d) While climbing up the Alps I may stuck behind some cager
and at very low speed I'd rather have that torque extra
e) I just want it - OK?!

Thats what I said...that's why I am not really interested in changing the exhaust now...have had this issue on every bike I ever did exhaust on...

Are there any exhaust manufacturers who have a reputation for systems that don't alter performance that much, but just try to make a system that looks and sounds better than stock?
I've never been interested in most of the aftermarket systems for the same reasons that you guys have mentioned. Sounds like if you want to increase HP, you lose bottom end... I have no interest in that either. How about a system that just looks and sounds better and is lighter than stock? Seems like that would be a hot seller.

I would think that if you could find a system that keeps the primaries smaller diameter and longer, with a properly designed 4/2/1 configuration, you'd have yourself a peach.
Bear in mind though that the 14 is supposed to have sufficient torque down low that losing a bit shouldn't be catastrophic...

So did the Busa and it was catastrophic...trust me...I posted my dynochart on a thread here...

The 14 has the most torque of any sport production bike...For racing you need the HP up top...If you want torque for street cruising then Muzzy would be your best bet...Dont forget to drop a tooth on the front sprocket and have fun doing rolling throttle holeshots...
