2019 GSXR 750 Dyno Tune w/ Cat Delete Pipe & M4 Slip On Exhaust- MOORE MAFIA 

Can you get him to tell us the link for the cat delete?

Fabian Cruz What’s up man. I know he used a few of the links on RU-vid. I deleted my cat too. I’ll find the videos

I deleted my cat by copping it off and welding a titanium mid pipe for a slip on. You can take it to a good welder, if you have titanium exhaust get it done.

ry ry now MJS has a midpipe that attaches to the stock bolting system for the catalytic converter. That’s what me and this guy used. It took me all of 15 minutes to cut and put back up there.

@@mr.renaissance8299 Just bought this mid pipe for my bike (gsxr 750). did you do anything special where the pipe meets the header pipe to seal it off? sounds easy enough.

THANK YOU! GLAD U LIKE IT!

Have you ever dyno'd a gsxs1000 to see what power they make? I have a GSXS1000F , full M4 exhaust, K&N filter, healtech quickshifter, woolich racing ecu flash with just a street tune (never been on a roller). Always been curious what it would make, feels like it has to be in the 150+ area

Can a 2003 gsxr 750 get a tune?

@@Hoktew ofcourse it can

@mtb supertroll he said in video it had an M4 slipon and cat delete.

Did you delete the CAT???

@@stopitskiiiuuup4006 🐈🐈‍⬛

Did you get her to make 150whp?

Difference between what and what?

@@prelude12341 cat and cat delete

I agree this vid & sound is perfect.. who needs a go pro when you have a Note 10!!?? (I dont have one) lol

So is is better with the CAT off???

Do it.

Yes it would

K8 is King!

If you do you will love it. Fun bike. (Gsxr 750).

I’ve had two of them, Love the bike so much. It’s a perfect happy medium.

Yeah was my first entry into the super sport category had a 2018 model miss that thing is great and can stay with litre boys to a point too when iwas driving iwas keeping up alrighttttt until that mid top end smoking 600s everywhere hahaahaahahah

Thanks Www.MooreMafia.com/ecu-flashing-service

Nice! im about to pick up a 2020 750, is the mid pipe the one that deletes the cat? if i go this exact exhaust setup, could you tell me which pipe i would need to buy please if you have a chance? looking to delete the cat and do this M4 exhaust. Any response is appreciated!

@@redline350zHR MJS performance is gonna have a mid pipe that is used in place of the OEM catalytic convertor once you remove it. There is a huge amount of videos regarding this process and im 100% confident you can do this if you have minimal mechanical skills. You send your ECU to chris in SC, while its out getting flashed you do the midpipe and muffler install and when the ECU arrives you plug it back in and cycle the ignition key 2 times to allow the ECU to register the values on the memory and you can then ride the bike with zero regrets. You will be in a group of very happy motorcyclists. I keep a permanent grin when i ride now!

@@ComputerCapone THANKS !!

prolly need to wear ear plugs, i do.

I put same exhaust on my Zx14r (full GP system) and I just love it !! It’s not my daily driver , I just love the exhaust note , pops and everything in between … love these M4 exhausts !! Good choice 👍 great value

What happened to Micron? Out of biz?

Hi

Www.MooreMafia.com

Also do you recommend doing the pair delete when you get the ecu flashed?

Hi I got the same set up on my L6 600.You can rotate the spring for the exhaust servo to fully open no need to take off.If you are flashing your ecu yourself you can disable the O2 sensor if not ask your tuner to disable.I went with ftecu flash kit and had my local dyno tuner re flash the unrestricted tune to make more power and smooth out the fueling.Went from 103 wheel horsepower to 112 wheel horsepower ,if you are dyno tuning it absolutely critical to plug the pair valve so the dyno tuner reads a correct air fuel ratio.

No you didn’t mess up the engine, it’s fine. By cutting off the pipe it changed the back pressure. That being said your air/fuel ratio is going to be different then when the bike was tuned with the converter on it. The computer is trying to correct it the best it can but will never do it till you show it how by getting a tune .

No, you’re still moving forward as you decelerate

.. it was a joke. A bad joke. But a joke.

Great question Steve ..are you sure this ain't Rickie asking hahahah ..would love to know the answer to that as well

Come back to tell how it went. What changed and what was done, and so on. Would be good to know.

He had an issue with the torque part of the dyno. For some reason it wouldn't read from the ECU to the software. No biggie. This bike is a great bike but has a few issues with the smoothness of the throttle. It seemed jumpy with no throttle just idle speed in 1st. That's gone. Big plus for me. In the HP part. I didn't increase much. Which for this bike it's to be expected. From the factory it should be between 112 brake hp and 114 BHP. It should lose up to around 10% from the crank to the wheel. Correct me if I am wrong.... its initial pull was 101 HP at the wheel and after flash and dyno was 105.89HP. I got a new decatted exhaust and I have a radiant cycles shorty GP exhaust. The bike is extremely LOUD. I love it. Had the pair valves blocked off, and a KandN air filter. Other than that it has fantastic response after the flash and tune and I greatly appreciate all that Chris did.

@@shawnfraley8056 Very interesting. That a decent percentage anyway. Should be considerbly better if he smoothed the curves also. Did he do anything for the -6° ignition at the first 4 hears, and rid of the speed limiter at 6th gear too?

All I know is that my fuel is smoothed out and has no dips (cutouts) from what I saw on the screen.

You can prob squeeze a little extra power out of the OEM setup but it won’t be much. The real gains are seen with a full catless exhaust, race filter, smog block plate (when applicable) and THEN tune it.

I am taking my 2018 GSX-S750 to him this afternoon.

That’s awesome!

Already dropped off

What days were those????????

You sniffing glue again Rickkie !!

Thompson alot actually I had a 2013 gsxr 750 with a full exhaust, power commander and a pair valve delete and i would hang next to stock 1000's all day long, especially if you know how to ride.

@@adamwelles5502 would have loved to see that... I've never had a 750cc anything within striking distance of my '05 ZX10R with just a Slip-On. They aren't within a Zip Code on my current setup. As you stated, riding skill does play a huge roll. Equal riders though, 750 stands no chance at all.

@@bacchusthompson5834 I've had liter bikes, 600's and 750's and the 750 is by far the funnest to ride bike in my opinion. The 750 being in a 600 frame, makes it where you can throw it around in the corners and all that good stuff and you can wheelie em easier then a 1000. And still plenty of power. My 750 would do 180+ mph all day long. On most streets you never really have the room/space to get the full potential out of a liter bike. But hey everyone's got there own opinions.

I want to know this answer also. Ive heard although that is the hp numbers youll get, the ECU flash smoothens out the throttle throughout the rev range and you also lose the weight of the heavy cat

I dont think it will. If it does rub, you can rotate the neck of the M4 a few degrees clock wise before tightening the clamp. Google the pic of it and you'll see what I'm talking about

Good advice!

Moore Mafia that would be a good video to show the before and after results

Bro what are those? Sorry for the question but i havent heard of that

@@redline350zHR they’re basically intake runners inside the air box, the gsxr 750 has a mix of long and short runners, where as the Gsxr 600 has all short runners which help high RPM horsepower. Look them up on eBay to get a better idea of the difference
