Good day

Does anyone have any idea on upgrading the performance on the KRX at this time?
Muffler
Tune
Etc...
I know the talk is turbo coming, any ideas on that as well.

Just want to hear what others may have come across and the HP gains it may add.

Thanks

Nope, Nada and I doubt that Company is still working on a turbo... imop.
I'm also interested in a tune or clutch kit would like to get rid of the hesitation when I stab the throttle
I would like to have about 40hp extra. Perfect imop, 150hp.

I have a local guy.. who is a programmer, spoke to him today about doing clutch work, harden springs etc .
Also spoke with some peeps at Trinity racing and they have tested the "full" exhaust and adding that with their programmer will add 15HP
Cost in :$1100 then I'm using local programmer guy to do clutch work he has verified it will work along with clutch work possibly adding an additional bit and really getting the hesitation out.. etc..

Their is some hope, will keep all posted...
Love the machine..

I'm with you...
My magic number is 140/150..
Then I wouldn't ask for anything else.
Wasn't looking for crazy horsepower numbers honestly just hoping I could get a tune or clutch kit or both and get the throttle response where it should be

I have a Trinity stage 5 full exhaust in route..
I have sent my ECU to get flashed to match:
The full exhaust
New air filter
93 octane


What I get:

Speaking to them personally, with stock u gain 6 up, with exhaust in consideration and above, should push lower 20's up.
That's a big step and not alot of $ to get there, as I spent only $750 for exhaust.
Also with flash, throttle response and rev limit changes as you can see from link...

Just thought I'd post this, and next week or so I will repost on thoughts..

So we are looking at 10hp increased? I want to be at 140+! 10hp would even up races with competitors of course and help the bottom lag Im sure.

10 hp
I had heard 20, but good thing is, get rid of that ugly muffler off the back and add some sound, really helps to man..lol

Rev limit, and less lag on take off, getting that direct response.. hopefully feels good!
I want to hear a sound clip of the trinity exhaust. That’s what’s holding me back from buying one right now.

Once I get everything installed I'll get you one
Any idea what the weight is on the Trinity? When browsing exhaust's, I saw something on the Graves web site that showed the stock muffler at 25.4 lbs. and their muffler and cat delete at 7.8 lbs. I am much more intrested in a full system rather than a slip on type. I like the Trinity price much better. I did see somewhere that a guy had the Trinity but removed it from the excessive noise. I really curious to see what you think about it. I would imagine that there is a fair amount of weight savings also.

I will try to also post weight differences as well oh, I spoke to Trinity racing I did not get the actual weight but it is a significant difference

I weighed stock muffler headers and all.. 58lbs.. she's a beast! Trinity full exhaust will be in today.
ECU being shipped out today to get reflashed..
Will keep everyone posted

So does anyone know what you gain with just a slip on vs a full system

This shows just stock without any changes to the exhaust.. which is around 6 horsepower.
Rev limiter gone
Added throttle response
Fuel balancing

I do not know about slip-on but for the full exhaust I am looking at low 20 horsepower gain with the flash and full exhaust.

If I were to guess. I'd say u gain 5/6 hp, however u will still need to fix fuel issues adding it, so doesn't run lean.. and maximize what your doing.
I hope that helps..
Thanks for the update. Really intrested on your thoughts of the Trinity system. I would love to get some added performance and shed so lbs too.
Yes I'm looking into a reflash and exhaust wasn't sure if I'm going with a full system or not but definitely interested in that sound clip
