Another great video. I like the intro you did. Nothing surprising about those dyno results, but thanks for testing for science and sharing your results. I put the Greddy on my RF and I’m loving the sound and better looking tips.

Thanks for the positive feedback. I thought I'd try to make the beginning a little fun. I do like the Greddy's dual exhaust tips, and nice deep tone - it will be interesting to see what impact the mid-pipe has.

Finally! I have been waiting for this video for a while!

Great video... thanks to share... for my point of view the result is good... I just install the Greddy Supreme Axle back... and I'm happy to see no loss in a stock ECU mapping... Thanks...

Thanks for the watch, and comment. I'm pretty happy with it too... spot on to what I was hoping for. Now let's see what gains we can get from the mid-pipe.

Great video! I also own a 2019 RF and love it. It would be nice to have a little more sound from my exhaust so these videos are very interesting to me. Keep up the great content!

Thanks Chad - excellent video and well presented. Looking forward to the tests on the GWR Super Street and Mid-pipe as well. PS I'm leaning towards getting the GWR mid pipe soon!

Great video Chad. Are you considering adding a header in the future? I know some of the ECU tunes for the ND2 require a new header in order to work. Just curious if this setup with a header would be too loud for normal use.

@TheLemonFactor

3 жыл бұрын

Thank you. I’ve considered trying it but only with a proper tune. But I do think it would be pretty loud for me as a daily driver 🤷‍♂️

I enjoy your videos. Would you say that the replacing the axle back alone would provide any noticeable gain? I honestly do not take my 2017 RF over 4,000 RPM's much, if at all. Thanks again.

@TheLemonFactor

If you’re not taking the car over 4K RPMs, then no, I don’t think you’ll notice any power gains from an axle-back only exhaust.

Before the next install, can you drive it around with a camera inside the cabin so we can hear what the Greddy sounds like from the driver's perspective?

nice series!! I have the GWR SSST, But I want slight more HP and torque and thinking if the midpipe would do it, I am not sure, but 5-10 more HP would be lovely . I think a header would be too much for me

Does the louder exhaust add to the feeling of the car ?

@TheLemonFactor

3 жыл бұрын

Depends on your definition of "feeling". Although it's minimal power gains, the sensation is enhanced, especially when you're higher in the RPM band, near redline it feels "zingier". Hearing the deeper tone makes me want to hold the gears longer.

How were the conditions between these dyno pulls and the original, ie temperature, humidity, etc.? All of these can be a factor in the readings you get, and with such (relatively) close numbers it makes me wonder what affect outside influences had on the results. By the way, big props for using dyno results properly by looking at the differences created by your modifications and not focusing on absolute peak numbers!

Top of 4th gear is high speed. Why not 2nd and 3rd gear pulls

You always want to dyno a car in the gear that gives the closest to a 1:1 ratio for the most accurate numbers.

@TheLemonFactor

3 жыл бұрын

It is common practice to select the gear closest to 1:1, of course within limits. The consensus from Miata tuners seem to be to run your pulls in 4th.

@TankRust

@@seanmarshinski8022 Yes you are correct. However in the case of the Miata, doing a ramp run in 6th gear would mean holding full throttle and load from 50 mph at 2k rpm all the way to 189 mph at 7500 rpm. I'm not sure that would be in the best interest of the dyno or the car. Even a 5th gear pull would be from 40 mph to 147 mph. Given the lower power of the Miata, the dyno operator probably settled on 4th gear to keep the speeds between 30 mph and 120 mph and the ramp runs of reasonable duration.
