Hi Guys,

Am thinking of getting an aftermarket exhaust for my KLE (06 reg) does anyone have any thoughts as to what to get / avoid?

cheers

have only just found this place - its ace! a wealth of information!!!

I will hopefully be going down the less restrictive exhaust route at some point,
thing only pointer I have heard so far is that when an aftermarket exhaust is fitted, it may not be compatible with the aftermarket centre stands.
Depends on priorities I guess!

I was looking at a laser produro system for my 2006.

The road legal system was £350 and the sport £300. It says that no re-jetting is required but ive heared that one before when I fitted an akrapovic system to my old zx7r.

I think that I will just wait until this system rusts before I change.

If you fit a less restrictive exhaust, it will flow more, produce more power, and run lean....
i agree take all claims with a pinch of salt.
my plan, is to use gpz settings as a benchmark, so if i keep the kle cams (don't need a screamer) and jet somewhere between the two, i shouldn't need more than a quick go on a rolling road to double check things.

I have fitted a Staintune pipe to my KLE and it makes a big difference. It is sort of a slip on so you have to cut the original system just behind the right pillion peg plate and join them with the clamp supplied.

It has a removable restrictor that can be taken out whenever you go offroad.

And the difference in weight is incredible. Very recommended modification. On thursday my bike is going for a dynotuning and new dna air filter.

I'll keep you posted.

good stuff, when having it dyno'd, can you ask them to tell you the final carb settings for this set up? ie main jet size etc?
cheers

Sure will.

I will get the dyno print out too. pity I never got one with the original pipe too.

This is the Staintune pipe:




Please note that the one in the picture is not my bike.

Apart of the exhaust I have fitted an "Eagle Screen" extended touring screen, centre stand, givi topbox, grip warmers, renthal bar, hel steel braided brake lines, synthered pads and a new front disc. I would have loved to get the "Braking" waved disc but they don't bring them to Australia.

The bike is back from the workshop and with 5 extra ponies and a little increase in torque.

The mechanic told me that I could gain even more is the exhaust system is replaced to get rid of the catalytic convertors in the extractors or something like that.

The KLE has 3 cats and restrict the bike a lot but I decided that I had already eliminated some restriction and don't want to increase the emisions for a little extra power, at the end of the day it is not a race bike so no need for it.

The DNA filter went in and the airbox was modified, so the little snorkel intake was taken out of the box and new holes were drilled at the back of the box too. As many may know by now, K&N doesn't make and specific kit for the KLE but DNA does and they have very good reviews.

The first run in the dyno indicated that the bike was running too rich, maybe because of the premium unleaded (98+RON).So after fine tuning the carb the 134 jets went in but it went rich again. Probably because of the restrictors and because the dynokit was designed to be used in conjuction with the K&N universal kit and regular unleaded. So he tried 130 and finally settled for 126 after asking me if I wanted to keep running the bike on premium or change to regular. I rather using premiun because I had bad luck with getting bad batches of regular that made my car run like crap in a couple of occasions. But if you are running on normal unleaded the 130 are good if you keep your stock exhaust or 134 for derestricted exhaust and mufflers and unversal K&N air filters. Remember that this Dynojet kit was designed in the 90s when the emission laws weren't as tight as they are nowdays and it hasn't been updated since then due to the fact that they don't get the newer model KLE in the USA. This is the reason why the kit is sold online as 1991-1998 and for European models only.

So here is the dynorun sheet with before and after:

Before in blue with stock airbox and filter and carb. Only staintune pipe in it.

After in red with DNA air filter, modified airbox to improve airflow, 126 Main jets and the staintune pipe


My mechanic also ran the bike without the muffler restrictor at the end of the staintune exhaust and it increased the noise a lot but the gain in power was almost non existent. It was very much the same graph but going rich again at the high end of the revs range. So if I take the restrictor out it will be to piss the neighbours off or to interrupt the mobile phone conversation of some stupid drivers
