Doing an oil change on the 929 today, I found it hard not to admire the headers on this bike.....a nice piece of manufacturing art.....

I can't believe some of you squids unbolt this thing of beauty and give it the heave ho.....
I think I would at least hang it on the wall to admire....

I the looks of the stock 954 exhaust. I don't think I've seen an aftermarket that I think is better looking, but if I currently had the $$ I would go w/something just for the added HP.

I can so picture you out there in your garage, bike centered aloft between your two Pit Bull stands, while you fawn over the headers.

Hehe, j/k.  I think the stock tubing is pretty nicely done as well.

I'm still looking for someone to post what sort of power increases they got on a 954 with the addition of full exhaust (i.e. Arata, Hindle, Akra, etc.) and a PC; unless the power leap from the stock ~130 is pretty significant (say, to the mid 140's or thereabouts), I'm not sure I'd ever go with a full system. The loss of useable torque and power through the low and midrange with the HTEV equipped OEM pipes wouldn't be worth it for a road-going motorcycle IMHO.

hey Chain,

  I just went from 130.3 hp to 146.1 with a Micon Serpent and PCIII. Torque went from 68.4 ft-lbs to 73.5 ft-lbs. Everywhere after 4000rpm had an increase

p.s disregard the dips at 4k and 6k as they were caused by a slight glitch that apparently appeared in the tacho / computer interface

Z's power increase was BY FAR the most that anyone has seen with a full system and PC. When I got an extra 16 the tuners acted like it was amazing.....this place has mapped loads of Blades and it was the biggest increase they had seen.

The dip at 3-4K is real, can't you feel it?  It is related to the collector design.

I was on the phone with Micron (about something else) and complained to them that I thought their surface finish choice was ugly.  The guys said that Stainless discolors like Ti.    I said sure pal, it just discolors to brown!  I will say, the hydroforming of the Serpent was really impressive to me looking at it from a manufacturing perspective.

Anyway the stock header looks sweet, but it is heavy and somewhat restrictive.  Have you ever seen a full Ti Yosh system after its been run on a racebike?  It looks sooooo coooooollll!

Looks more like something that experienced re-entry, than an exhaust if you ask me....

Hey LTL......I wasn'T talking about the dip from 3-4k.....if you look at the blue line there is a small dip at 4k exactly and 6k exactly.....that is what I was referring to. I can honestly say that I don't really notice a dip in power at 3-4k.....but I do notice that the big bulge in power that used to be there is gone.....but now it seems just to build steadily.....no dips, or sudden rises either.

My arata Ti system looks wayy better than stock if you ask me. The primary tubes, crossover tubes and collectors are a deep purple. As far as the loss in torque, i can't say that i notice it. If you roll on from any RPM, you are out of the area where the Dyno charts show a dip, in fractions of a second. my seat of the pants dyno can't feel any loss. The top end rush is more than worth it, and the sound.... it has a funny crackle to it, a bit like the moto GP three cylinder machines (aprilla, suzuki). At least thats what it sounds like when i am on the bike.
