Cat Bypass - The Next Step in Heat Reduction

[Magdave]

Central Florida PowerSports did a CAT bypass and they show the difference in temps with a RT-S. Here is the video of it. I do not know how to link it to the page.

Who is selling these? I need for summer time riding in Deep south texas.

Dang tha tis the first proof I have seen of the temp difference. I wish it had been shown on a 2013 :banghead:

On the 13s one should still wrap the y and header pipes as well as possible to really make a difference in the summer heat. My glove box went from 135F down t below 100F and this at an abient temperature of 85F.

I would bet the 2013 temps (both with and without CAT) would be significantly higher. Still impressive as to the difference. Did like the sound with the ACK but would like to hear it on the 2013.

FYI jcthorne emission testing is still done to M/C in parts of AZ and CA. Depends on County you live in.

cat by-pass

what does the by-pass do to the 2014 rt with the 1330 motor

 

[Bob Denman]

It makes it SOUND better...
Seriously; it does remove a large source of heat from the bike...
But is it absolutely necessary to do tis? :dontknow:

Will see if PittBull has a temp gun next Thursday if I get a cat bypass done on my 13RT. Should be interesting to see the difference Will try to get a video of the results.

I'll ask that question of my dealer also. I'm due to have my new pipe installed on mine in a few weeks.

For me, removing the cat is all about reducing heat. Since I have a 2013 RT, I consider that an important safety issue - not just a comfort issue. Any other advantages will be icing on the cake. To counter act my Spyder adding more greenhouse gases to the atmosphere, I intend to make a concerted effort to eat more beef. One or two less farting cows on the planet should more than make up for the effect of my Spyder after the bypass is installed.

Too--Shea robmorg!

this is probably very true but by myself only having had a 2012 I wont comment there, however even on the old frame the issue still remains ,I have wrapped pipes ,added cat bypass also wrapped,and still dealt with boiling gas ,and fuel smells, there simply isn't enough air flow through engine compartment the heat from the motor alone is to much ,and when shut down the heat soak is so great you could restart to circulate water and run fan 3-4times to help lower this condition.

The difference is the newly designed frame for the 14's that they used in the 13's with the 998 engine. The frame was not designed to work with the 998. The tolerances are different and the add on mounts to adapt the 14 frame to the 13 engine (998)
puts the exhaust including the CAT in or around the tupperware. The exhaust on the 998 flows around and down the engine, then through the CAT, back over to the exhaust pipe and then the muffler. On the 1330 the exhaust goes strait down and out, back to the exposed CAT then the muffler. Thus avoiding all the exhaust piping and CAT inside the cowling or tupperware. WRONG FRAME FOR WRONG ENGINE.

I'd be looking at adding JT's air filter replacement. you wouldn't believe the amount of space it opens up dumping that big old air box. :thumbup:

That's the last thing on my list of things to try, if after I get my cat bypass installed, I'm still not satisfied with the heat level. I hesitate to do that for two reasons. First, I don't think I'd like the sound with that mod installed. Secondly, I'm only one year into a three year warranty, and my dealer told me that if I did that, BRP would likely not honor the warranty on most engine components. I'm hoping that with all the other things I've already done, the elimination of the cat will get the job done for me.

you are not restricting air flow so I don't see how your dealer would say BRP wouldn't honor their warranty. in fact you are giving the bike more air flow. i am only into year one of my four year warranty as well.

as far as sound, yes it is slightly louder but only really when you get on the throttle hard. you get used to it pretty quickly. i think the results far out weight the cost. YMMV

I have a 2014 RS and I'm a big fan of mods and will be doing the cat bypass. I already have the VooDoo twin exhaust and it feels better already. I have ridden on a 100 mile trip and haven't had any heat issues "thank God" :thumbup:. However I will be doing the bypass for the shear feeling of having modded it :doorag:. As far as the warranty is concerned there should be no issue unless the mod that has been performed is in direct fault of whatever may be the issue. To all whom want to mod your ride, like Nike, "Just Do It".

I like your plan with the Cows...

About the whole "Greenhouse Gas" thing... :shocked:
I'm certainly no chemist... or much of anything else. pps:
But if exhaust gas used to be primarily Carbon Monoxide; didn't the converters change a lot of that over to Carbon Di-Oxide: the gas that everybody seems to think is the REALLY bad one? :dontknow:

(Honestly; I don't know, and am just asking)
