just sold my r6 and proud to be part of the gixxer 1000 club. lol. i just got an 05. pretty much stock except for a slip on yosh pipe. looking to do a full exhaust and power commander asap. then later a gear change. can anybody recommend what they think the best exhausts for these bikes are and with the exhaust plus power commander how much of a gain am i lookin at. thanks.

ps i'm not lookin to break the bank so any of the more expensive exhausts are pobably out but feel free to give input on those. maybe you'll change my mind

I call bullshit on this one, your octane is not increasing hp with the setup you have so dont try and tell me it does.

So you picked up fifteen horses with a system, filter and pc. I'm a little skeptical with out a dyno sheet. Most k5 and k6 I have seen netted high 150s to low-mid 160s.

Your in bmw and new zx10 territory

^hahaha - It's all about what the "customer" wants to see...Could you imagine taking your bike into a dyno tuner and having a base run come up at 150 and then after throwing PC / exhuast etc at the bike, getting a 156hp result, with impeccable fuelling ? shit - they'd tell all their friends that the tuner was hopeless, didnt know what he was doing and never go there....lol

ive had many cars put on the dyno and tuned and one of my sixs but not the 1000 yet. i would much rather get my true numbers than some fairy tale make believe figures.
To be honest and just for the record I didn't say the octane gave me more power just stating the fuel in the UK is 95.

The dyno figures anywhere can be fudged to make you/the customer feel good. It all doesn't matter that much as long as your mixtures are correct it is running as good as it can.

My K2 made 145 rwhp my K4Z was 153 rwhp with increased to 164 with PC111 and Akroprovic Evolution System. As stated earlier my K5 made 173 and my K6 is BSB Spec and makes loads more. I don't really care how correct the figures are. When I ride it, it makes me smile!

not trying to shit on you but clearly your numbers are not corrected and that dyno has been calibrated to read high.

if your happy and it runs good then I guess all is well.
i just have not seen stock motor bolton modded k5-k6 break 170s. not saying it couldnt happen but improbable in my opinion

Well, you best bet is to scour Ebay for a Akropovic Ti full system. They discontinued the oval can for the new hex setup so people are selling NIB systems pretty cheap-you just have to wait for them to come along. Took me about a month and a shop listed two, I paid $700 for mine, the other guy got his for $400(!). Akra claims 14hp for this system, don't know how that will work out in the real world but if the quality of the exhaust is anything to go by it's certainly possible. The pipes are hydroformed and tapered, the welds inside where the pipes join are all ground clean, this thing looks like it belongs on a superbike-they were over $2k when they came out.

On a real dyno (from a racing engine shop, tuned so that they get within a horsepower of the official series dyno), the best I've seen out of a stock motored 06 is 158whp and that was with a trick Yoshimura full exhaust and stock filter, as well as an EMPro CPU (more power from a stock filter, BTW).

That's really, really stout to begin with... The stock 07/08 motor is capable of quite a bit more because of its higher rev range and more aggressive cams but on the street, the 06 just kicks it all over.

FYI, my motor dyno'd 174whp on that race dyno with 91 Shell, Evo2 Akrapovic, degreed cams, PAIR delete, 520 conversion, head work and bumped compression (with the stock wheel). Same bike says over 190whp on a local dyno (and I call B.S.) YMMV.

any idea what 158whp translates to at the crank?

When I bought my 05 1000 it had a full yoshi exhaust and I wasn't happy with it so I found a Delkevic ds70 slip on and kept the yoshi headers. Personally I think this exhaust sounds amazing and it only cost me 220 for a shorty (9inch) carbon fiber slip on and with the yoshi headers it sounds better then even the expensive exhausts. I have gotten nothing but compliments on it. Check it out if your still looking for an exhaust www.delkevic.us/

The last two weeks I have had a Motty AFR installed and gained 10 Hp and 7 ft lbs of T . The final run on sunday netted 149.5 and 76.3 on a Dyno that is regarded as one the runs 10 per net under all the other dynos in the area , I put a set of brisk plugs in. the same Dyno and tuner Mikes works on 90 percent gixxers and has like 20+ yrs and did a sweet job on the generic install , and the 10percent # makes sense as the last time I ran it 30,000 km earlier it went 154.9 on another local guys Dyno so now my Gixxer pulls like never before I also installed a set of phat Opp intakes and FUK it pulls HARD never ran this good , so on anybodies elses Dyno it will be pulling like 165 and 84 mods are TI Force half system big mid pipe, k&n pair mod , brisk plugs , factory pro stacks and the phat intake :) Nets 100rwhp at 7K on mikes Dyno :) and 75 lbs T from 7.5 to a peak of 76.3 at 9.5:) things sweet pulls the wheel in 3rd (stock gearing) over any little bump at 100mph sssoo sweet next mod is a R6 throttle Hehehe

My bike has the Leo Vince Titanium, Filter and is custom mapped. The guy who did it is considered a guru (in Norway :)), and mappes the injection live on the dyno directly for each 100 rpm (no powercomander).
His "bench" is supposedly very correct. In DIN hp my bike did 162 stock, 168 with the mods and 172 with mods and airpressure to the ramair. The DIN (Deutche Industri Norme) hp is a little less worth than the US hp I think....

Here in Europe Suzuki says the K5 is at 178 hp (DIN) at the crank. Up the 162with 10% and you have 178, so this should be accurate.

the dyno I belive in UK is racedevelopment from Tim Ridey, reads less than those of Cressent....

on the topic.... I have seen good gains with a full exhaust from Arrow full.
I have one and the quality is very good.

Do not use power commander, or AFR or bazzaz.

look guys i own a k5 1000 and live in quebec canada and i ran the bike on the dyno friday ... and it ran a 158 rwhp and 82.1 torque corected uncorected it ran 164 and 85 so who ever tells me the bike is supossed to run more its bolony they did 41 runs that day bczu they werent impressed and to top it all off when i did my run in february with only a k&n filter and yosh slip on it ran a157.15 rwhp and 77.6 pounds of troque corected so with a full jdm yoosh and bazzaz z-fi qs and z-bomb tre i only gained 1 hp to the rear wheel and 4-5 pounds of torque corrected so guys who ever says they bike run over 165 uncorected hp on a stock motor is bullshit ...

You're bang on. Not the 05/6 for sure. 158 is about the best I've been told, and that's with exhaust and tuning. And BTW, despite what people have said in here, Canada gets the same bikes as the UK does.

Also, yes, Arrow makes more power than Yosh on the 05/6 engine. This has been known since the early days of SBK racing, where Arrow's stuff was better than anyone's right from the start.

The only way you could tell if the bike gained if you make a before and after dyno run, same day, same tire.

My personal opinion is that yoshi is BS stuff.

have runned stock K5 with slip on side by side a full system yoshi and they where even.
then my K5 with arrow full was 3 bikes ahead.

How's this, bone ass stock (to the original plugs with 9k miles on em, and original air filter again with 9k miles) I puts down 152 and 75 ft lbs. This is without a gear, without a TRE, Showroom stock as it comes (minus a fender eliminator).

Off of a PC3 and exhaust you should easily see a 12-17whp gain, if your tuner is worth a damn. But, we all know numbers are just numbers, its what you run on the track.

Lowered with a -1 front sprocket and TRE flash I'm running 9.874 @ 144. These bikes are no slouch!!

Like i said earlier u do not gain 10-12 hp at the rear wheel that easy buddy i work for ferrari quebec and are dynos r the best in the industry my bike bone stock ran a 151 at the rear wheel and dyno tuned by one of our own engineer that tunes our f430 chalenge cars so dont blame the tuner its real facts not bullshit that everybody is reading higher dino readings just to make the customer happy my gixxer is 158 rwhp and im still head to head with a 2009 zx-10 with the same mods can u briliantly tell me y if ur such a genius and easily capable to b a hater ... Btw the zx-10 ran 172 rwhp so plz tell me how we r head to head genius MJK

Wow, first off don't get so bent out of shape buddy, its just the internet and I'm not saying you have a small dick, because frankly, I don't give a flyin' shit.

And simply, you must be a better rider. What times are each bike running? Post up slips of each, please along with a full mod list of each bike. Also, have you ever compared the power under the curve (you being obviously superior to me should have figured that out)? Working on race cars you should know this is the power that matters, not peak power. The K5/K6 Gixxer has one of the, if not the absolute best midrange powerbands of all 1000 cc sport bikes.

I'm not a hater, just pointing out obvious facts. You don't know me very well to be calling me a hater. Bet I have more time on a dyno than you think :twitch

P.S. Last time I checked, we're talking about Suzuki's not Ferrari's. :scratch

P.S.S. Get off your high horse Mr. God Complex. :flipoff

gsxr 1000 - full yoshi exhaust , k & n ,bazzaz z-bomb tre, bazzaz zfi-qs,
zx-10 - full akropovic stainless, powercomander 5, b & c filter that is all
i beat the bike off torque i have 82 pounds of torque when he ha sonly 73 ... hp is top end power but the point once again is that u dont ever c 165 rwhp on a gixxer 0506 corected hp ... uncorected u can c up to 167 uncorected hp ... tuesday i will b recieveing the afm module from bazzaz that might go get me 1 or 2 extra hp at the most bcuz weve been doing the dyno tunning manually now we will try doing it with the afm module which gives the air fuel mixture a straigther line on the graph so bike will run sligthly better then wat it has ran second i dont do quarter mile i did once and it ran 10.2 and the zx-10 ran 10.6

who cares how much horsepower your bike has or how much mine has...this model is faster than shit. 90% of the people out there cant even take full advantage of this machine. go have fun on the track, where i constantly see 600's taking down 1000's every weekend...it all boils down to the rider and his ability.

for the record my k6 has 162hp. k&n, pciii, japan yosh slipon.

as long as its back from the dead.. may as well do some poking..lol
my 06 1k bone stock put 151.44 hp and 76.38 tq with hp peak at 11200 rpm and tq peak at 8500 rpm. on same dyno with same tuner and full arrow full TI comp system ( bsb spec system) race air filter and custom tune made 168.03 hp peaking at 12800 rpm and 80. 08 lb ft of tq peaking at 9000 rpm.
so in teams of peak to peak gains of just over 16 hp and just under 4 lb ft of tq. which is very impressive.. but not as impressive as the areas under curve that show much bigger improvements.stock the tq curve was good but somewhat humped and didn't hit 70 lb ft until 6k and then fell back under 70 by 11k. now it is flat as a table and hits 70 lbft just under 5k and doesnt go below 70 again until 12k and has a plateau of 80 lb ft from 8200 to 9600.
the hp under curve is much improved as well when stock the power fell off very fast after peak ( by 12500 was back below 140 hp ) now im over 100 hp by 7000 stock was just over 90 at 7k. and keeps climbing at a faster rate as well as carrying the power for several thousand more rpm. im still over 160 hp at 13k. so if you want to look at the top rpm changes its huge at 13k im over 25 hp over the stock set up. but most importantly.. everywhere thru out the rpm its more which is where you need it most. and i know all dyno will give diff reading and may or may not be the actually number it shows, but more important is its the same dyno before and after to show the changes made from the set up and tune. it has been on a few other dynos for fun at diff bike events and has always been within 3-5 hp of this on each one. some were more.. some were less. so not sure what the dynos read where everyone else is from but i know there are several other k5/k6 in my area that do make 160+ with stock internals.. so who ever says high 150s top .. i don't know about that

My mate ran a brand new K6 in formula xtreme here in OZ. It had stock internals, race filter, Agras full ti system and EM Pro. It was tuned and set up by PTR (they run the ASBK Suzuki team) and made 172hp on their dyno. Their dyno is rumoured to give higher numbers. Later in the season he had the ports cleaned up, compression bumped up and adjustable sprockets added and dynoed on a different dyno and ended up with 173hp.
