Cat Removal/Y-pipe install

Hi, Do you need to remove the cans in order to remove the cat? Thanks.

Yep. Sure do. You're gonna have to remove the cat cover as well and the rear tail section to get the stock cans off.

SCR1000, What kind of Y pipe are you installing? Where did you get it from?

SCR1000, What kind of Y pipe are you installing? Where did you get it from? Leo Vince. Got it from gpmotoparts.

Having some trouble with the Y-Pipe. It seems to be too short. It will not reach the header pipe when it is bolted to the frame. Not sure if I am doing somthing wrong or if it is too short.

Thanks. I hope the install works out.

Did the Leo Vince Y-Pipe come with a heat shield for that area?

Funny, did the same mod same day with same part :) First, you don't have to remove the tail section, if your fingers are not to fat or very short. In the pic attached (pic 1) you can see the two screws to remove under the rear seat and take out this shinny rod. Then you will have access to the screws holding the mufflers on the subframe without removing the tail section. There are two small, white parts you can easy lose, be careful. It seems to be too short. It will not reach the header pipe when it is bolted to the frame. SCR1000, did you use the original mounting part? You can't bolt the y-pipe directly to the frame. Pic is attached (pic 2), this way it fits perfectly! Did the Leo Vince Y-Pipe come with a heat shield for that area? No heat shield. You have to use the original, or without like i did (pic 3). The Leo Vince Y-pipe fits very well, looks nice in my opinion (pic 4) and there is a converter for two diffrent lambda sensor diameter and a plug to close the hole if you don't use the lambda sensor. The weight of this DeCAT is 1'110gr. Cheers!

Shin, Excellent post.

(euro model) ... i think the first 3000 rpm are just a little underpowered and the throttle is less crisp than the bike completely stock. I got only this mod... i've to try to give some more juice bi changing the setting in the gauge for the CO, cause for rpm higher than 3000 rpm it seems no more no less the same, pheraphs gears seems a little longer, and it doesn't wheely in second gear as simple as before!

oh,shin i got exactly the same colour scheme bike, by the way i noticed that there is a plastic teeth coming from the plastic heat shield of the tail with no practical use(in the upper section where the midpipe is bolted to the frame) that is going to melt cause it touch on the pipe. I thought it's best to put the same heat protection that's on the stock cat (the small one fitted using the metal wrapper) also cause the magnesium frame does not like high temperature...

Triplex76, looking forward what your try on CO adjustment will do. Let us know please. I can't tell if it's down on power in this rpm range, because i only ride there if i have to in city traffic...and this i try to avoid :) The 2 or 3 HPs you can maybe gain i don't feel, too. But i recognize something better throttle response (higher rpm range) and a bit more wheely tendency in first gear. I did this mod for weight saving, heat reduction and as a preperation for free flow cans, not so much for power gains. Thanks for your safety advice Triplex, but see, the original heat shield is directed toward the rider foot and doesn't protect the aluminum frame or the swingarm. So you should worry about my foot, not the frame and also, my feet are not made of magnesium and burn realy bad. For me, it was a big act of self control not to rip of every piece of plastic cover the first day i had the bike! To put back on this CAT cover would realy overstress my abilities. By the way, i like the look of the y-pipe. But i will have a look, if this plasic tooth is melted to the heaven of plastic and saved me an other 10 pds of weight :finger By the way, you have the euro model, too. Where are you from?

I Shin, I'm from Italy, I noticed somewhat better throttle reaction especially in A mode too, cause it's smoother and there is a little less on/off effect in low rpm ... but it seems to come from some HP lost the way it's smoother ... I noticed also that it comes up easier in first gear, but I got the sensation that in second gear there is less power , cause before, with the cat, the bike seemed a little more compressed (it went up by power) and the gears shorter too. by the way I'm going to ride the bike more to understand exactly if there is something changed in power and where ... let me know if you are able to find some more change in the way the bike reacts, I need some more advice cause it could be only suggestion and maybe I rode the bike in a not so good weather for power release! by the way, I need to say that I didn't like our bike colour scheme, I ordered the black/gold one's, but there was to wait 2 months, so I decided to take the white one and I must say that day by day it looks greater! I noticed you got the seat cowl, how much did you pay for? I see it's for the usa white bike, I found the withe/black leather one but it costs really too much here! :)

Thanks again!!

So, if ya'll could put the cats back in place, would you?

We can. But why should we do that?:dunno

* looking at the proximity of the y-pipe against the rear set and thinking I'd heat wrap my boots *

Seriously, it's about the same heat level i feel now. The cat was a lot hotter then the pipes, but shielded. No difference or a bit cooler now at leg/foot. But heat wraping my boots is interesting me now!

Thanks, but i know what i have put on my bike :) I will bring more red in the bike in the future. A bit like the white '98 model. Till now (2000mls) it's limited to back and front of the seat and grips :dunno Comes time... comes design... i spend more time in suspension and motor. Not to forget in riding! Two days ago i was in the Schwarzwald, germany for 230 mls. Ahhhh...that was fun! One of the best!

Shin, I like the lines of your mirrors. What kind of mirrors are those? Are they as steady as the stock mirrors at high speed? Can you see well while in a full tuck?

Hey ATL, i have this mirrors on every bike i did. They are steady at highspeed in the sense of they don't move away from airpressure as most aftermarket mirrors do. But they are vibrating. You can see in full tuck if you adjusted the mirrors in this position. They are small, look nice, highly adjustable and stable, but for a good rear view it's not thought. Personaly, I only need to see if a cop car is behind me or a fast bike. I order them from Micha, http://www.mibo-motoparts.de Shin
