I watched your video, ordered my part, followed your easy to follow instructions and I am so happy with the way my bike sounds now. going to get my ECU flashed by 2 wheel dyno works in seattle next week, the throttle is choppy now and I dont like it. and I want pops and bangs and unrestricted fuel mapping.
Good job and does dound very nice...... You need to reflash! Just because the exhaust valve is working means nothing! Reflash my friend and the motor will run much much better. Even with the stock setup a reflash does wonders. With doing such a major exhaust change it’s imperative!
Very good video, do you think it would be possible to cut only the first layer of metal and remove all the ceramic without damaging it? It is not appreciated if that part is loose.
I’m thinking of doing this my 2019 gsxs.. what are the main benefits and issues that come with removing the cat? And also thank you for that video! Very informative!!
Benefits: bike is a bit more responsive, feels more willing to go (few more HP). Exhaust is louder and somehow more pleasant to hear, but still in an acceptable range. Slightly using less gas (~0.5L less) Issues: exhaust sound. You might avoid core downtowns if police is strict.
@@grandjean5605 thank you for quick reply! I’m no where near a city so i might go with doing this! You think the sound will get annoying on long rides?
@@killajr51 for long trip yes, earplugs a must! Up to 1\2 to 1 hour is ok. But for long trip yes! For me, I always wear earplugs during long rides anyways, you know, you don't want to be deaf at 60yo ;)
just asking ---- whey -- you had a perfectly working bike faster then most is able to handle that don't upset your community or other on the road and now you haw a bike that eventually will destroy it self if you don't get it flashed and the only thing you then haw is more sound les km litter and if you are lucky a few hp more
Good morning sir. i watch sir your video wow is very good and informative thanks for sharing this. after you installed all, you also re- map or you use it as normal? i'm planning also to remove my 2020.thank you and ride safe.
I didn't remap the ECU. Engine runs just good as it is, the computer being able to somehow adjust good enough. When I previously removed the air flow reducer in airbox, I noticed it took about 300-400km to the ECU to adjust. So ECU can self learn and adjust a bit by itself and by deleting only the cat, the valve is not removed so back pressure isn't excessive. Consequently, In my understanding, no need to flash ECU unless you want a fine tuning. If the valve was deleted, then for sure you would need a remapping of the ECU. Cheers
@@MotoPrimeroGSXS good choice for a first big one! it's a reliable bike with surprisingly good specs for the price. You'll have really good fun! Ride smart, and safe 🏍️🏍️
I've heard that the exhaust valve is for nothing more than noise reduction, so what about removing it and connecting a servo buddy to prevent the F1 engine code? I mean, removing the cat changes the exhaust flow far more than the exhaust valve does, so if the cat removed does not require a remap, why would the exhaust valve removal? Thoughts?
Yes you can bypass the valve but i believe that then you need to flash ECU to refine the injection to avoid premature valves breakdown (back pressure issues). When flashing ECU you can also delete F1 light due to the removal of servo control, no need extra servo control. But you can put one too in case not flashing ECU. But honestly, in my opinion, money speaking, not worth it, as the gain in power wouldn't change much more. May be 2 or 3 HP more only, but mainly just a better mapping of the carburation. Right now, very satisfied with this easy mod!
@@grandjean5605 So......you're telling me that removing the entire cat converter did not affect back pressure? That's ridiculous.....of course it did! A whole lot more than just removing the valve, without a doubt!
@@michaelbrill6609 did i say that? Hmmm i think you over interpreted my words ;) but may be i should have had the word 'more'. To avoid 'more' back pressure issues ...
Congrats. I have no regret decat mine and now using Austin Racing muffler ☺️
Thanks for making this. Now I have a visual of how to do it..
Just did the cat delete! Came out perfect!! And I Absolutely love the sound!!! Perfect!!
It's nice isn't it? 👏🏻👏🏻
Ride safe!
is an engine tune necessary after cat delete?

Very good video, do you think it would be possible to cut only the first layer of metal and remove all the ceramic without damaging it? It is not appreciated if that part is loose.
No it's not possible with regular tools because the catalyst part is somehow welded inside.

Did you have any leaks where the mid pipe attaches to the stock headers? It looks like there was a small gap on the clamp cut outs
Nope, no leak at all. Fitting is quasi perfect.

Hey Jean, where did you buy this mid pipe? do you mind sharing the link?
AliExpress
Can someone tell me where can i also get a decat PLLSS

ECU flashing always best, but if you keep the exhaust valve the bike will still run very ok. I didn't flash ECU on mine and it's all good after 6kkm
@@grandjean5605 thanks for the response. Where I live, I dont engine have tuning facility. Glad to hear it will be fine.
Sounds crappy
