I’m glad to hear that you found it helpful. 👍 congratulations on the new car and exhaust ! Have you checked out the many other videos I have on the channel regarding Miata exhausts? I have several in which I take it to the dyno that you may find interesting.
Chad, once again your informative video has saved me enormous time and effort. I ordered the Cobalt exhaust for my 2020 RF GT MX-5. I received it two days later from Moss Miata using basic ground shipping. Installation was simple, and I love the deep tone. I know an axle-back exhaust doesn't add any performance, but it sure seems to breathe easier and quicker. I love it, especially the sound. Thanks again!
That’s awesome! I’m glad you found the video helpful. Congrats on the new exhaust. Have you seen the video where I dyno the Greddy axle-back? While not a lot of power, it did add some. What other mods are you considering?
@@TheLemonFactor Yes, saw that! I was bargain hunting for a deeper than stock tone and better breathing. It's my daily driver, and I'm not looking to provoke the police. I'm out of work and looking. So, I'm sitting tight. Down the road, maybe an AIO mod to improve the "infotainment" thingy. It's slow, and the warnings/beeps/notices among other features are annoying. I haven't researched anything yet. If I can get back to work soon, and pay this car off, I'll do MX5 cup car suspension mods, and maybe play with auto cross for a little fun as I age.
I’m sorry to hear that. Good luck, hopefully you’ll find something soon. In the meantime, enjoy your Miata - it certainly helps me relax and get my mind off things.
@@robertrucker9961 absolutely, more than ever. The Fab9 tune for 93 octane also adds to the experience. The sound of the Cobalt cat back pipe is perfect for what I intended. Quiet idle with a deep tone that builds as you get into it.
I went with the Hush-o-matic, with the can system. My can system has 4 levels of opening, I love mine, but your right, Flying Miata isn't always quick to reply.
Same , Hush O Matic sounds corny but really performs well. I routed a vacuum line all the way back. All Stainless Steel & its much lighter than stack but I didn't weigh it. Also the stock OEM muffler after about 18 months in 4 season daily driving the top had already started rusting. Love the sound & its not so loud when your not on the gas pedal. Neighbors will not complain & I leave at 5:00am every work day. For an active axle back exhaust the extra cost was worth it.
I just bought a '23 ND2 club. Planning on a full exhaust (4-2-1, mid pipe and Super Q). This has been very interesting. You provided the suspected HP/tq gains for the axleback, but not the mid-pipe, nor the long header. Loved the info, got more for the ND2? tks tj
This was extremely helpful. Working on evaluating my options for my ND2 RF. Any chance I can get a copy of the spreadsheet? I enjoy the videos. Thanks!
Thank you for the support. I have considered their products. The omission of them from the video should not be taken as an indication of any negative feelings about their products.
I’ve been running the Borla muffler for the better part of 1 year and it’s great with the top down (RF), but a bit boomy between 2200-2800rpm, which is right in the cruising rpm range. I’m going to give the HKS a shot and see how things change! (Both were purchased used on Miata forum with low miles)
@@TheLemonFactor Swapped mufflers in a shockingly fast 40 mins (not my first rodeo). The HKS is almost as quiet as stock, but has a unique sound. I noticed both the Borla and OEM mufflers had a pronounced resonance in the 2k rpm range. The HKS has more tubing (changing the system length more significantly) and almost zero drone anywhere. That said, I think the OEM headers lead to a 2750rpm drone, no matter what muffler you use. The HKS is a very high quality product. You save no weight and minimally change volume, but the unit is built well, produces an appreciable tone, plus the tips look tremendous. You install some heat wrap on the bumper, due to the close proximity between parts. As for my Borla, the flange is loose (not welded into place), and I could never seat it well against the donut gasket. I think there was a small leak, contributing further to the overall volume.
@@TheLemonFactor Unlikely. I bet all mufflers for the ND are within 5hp of each other, which is undetectable by even professional drivers (usually 10% margin is needed to be noticed). Performance can be better had with lighter wheels/tires, etc. I noticed when I went to lighter Konig wheels, the new tires (Michelin Pilot Sport A/S 3+) were several pounds heavier than the OEM Bridgestone set. I ended up with a heavier wheel package, which I definitely noticed immediately
You mentioned that your Miata RF is a 2019. Just checked GReddy's web site, and they list their GReddy Supreme SP as being applicable only to the 2016-17 (ND1 I believe) models. Is the same model useful, both fitment and sound quality-wise, for the 2019 ND2 models?
Hey Chad, I’m in the market for an after market exhaust for my 2016 mx-5. Any recommendations for a dual axel back exhaust with low pitch and bass heavy sound? I’d really appreciate your feedback.
Hey @@TheLemonFactor thanks for getting back so soon with a reply. I’ve been binge watching your videos the entire day, keep up the great work. I’m sorry for not being clear earlier, I meant an axle back exhaust with separate outlets.
All of these are for the ND1/ND2, model years 2016+, and specific to the 2.0L. I'm not sure that they'd fit the 1.5L, so you'd need to confirm before purchasing.
Welcome from France, and congratulations on your Miata. The Miata that we have as our project car (shown in the video), and all current ND2 Miatas sold in the U.S. have the 2.0L engine.
1st👍 You got the GT..perfect pkg. 16 Club owner here. This is a great review👍👍👍Goodwin Race, twin tips. 😎😎😎 Yes would love to see the Goodwin Race on the Dyno. Subbed.👍👍 Yep, rode in another ND with Goodwin Race, not to loud at all. Ok, Looking at exhaust too. Goodwin does Miata. SS quality, weight, hp gains and documentation. They have it together.
@@shiftintohigh5564 I've narrowed down my personal list of exhausts, but I'd like to hear more from others. However, Goodwin is in on the list. Thanks for the sub!
Great video! Thanks for the advice. I am looking to get a 2021 GT RF (I’m waiting for my color choice to come in) and I’d like to get a system with either central exhaust pipes (like the old C6 Corvette) or dual exhaust pipes (one at each corner). Do you know of anyone who sells such a system? Thanks!
What color are you looking for? As far as the exhausts, yes, I’ve seen some available with the center exhaust tip placement, but none with the exhaust tips placed at the corners 🤷♂️
@@TheLemonFactor - I’m looking for the ice metallic blue or the gunmetal gray, but with the white interior. Since this will be my spare car for weekends I figure the light interior wont be too much of a problem.
@@antoniomariacorreiajesus9019 Very good question and one that I'm currently working on. I hope to have a related video posted by the end of this weekend.
The cat helps to clean the exhaust gases coming from your car. Running without a cat should not harm your engine directly, but can indirectly cause issues with your overall vehicle performance if not done correctly.
Nope not for me. Drove one yesterday. RF version, brand new. Disappointed - very. Have now scratched that itch. Had always hoped it would be special. Very jittery, constantly moving gearstick , noisy, just too tiny inside, noisy, too much shudder on suspension, noisy, feels like its an old car, noisy, cabin quite nice but dated, noisy, nice red paint, noisy, like the 80's and no better, noisy, other than that a good car... what a disappointment... i really wanted to like it.. its just hyped beyond the reality.. and noisy if u didnt notice.....
Thanks for the information! I just bought 2021 RF GT and after viewing your video, I purchased Good Win Super Street Twin Tip @ $699.

Do you still like this exhaust?

i just bought my ND2 and i wanted more sound. This is really helpful.
👍. There’s a couple videos on the channel page in which we test out various aftermarket exhausts, with and without midpipes!
I went with the Hush-o-matic, with the can system. My can system has 4 levels of opening, I love mine, but your right, Flying Miata isn't always quick to reply.

I’m glad to hear that. Thanks for the watch.
Racing Beat makes quality Mazda parts. Nothing too obnoxious sounding and actual HP gains with certain setups
Thanks for the feedback... my last Racing Beat exhaust was back in the 1990s and I had no issues.
Watching this now makes me sad of what these prices used to be compared to what they are now
Now it makes me sad too 🙁
Really appreciate the comparison!
The technical drawing for the HKS showed 9+ kg, which is close to 20 pounds.
Well detail supportive material. Thanks!

Congrats on your new Miata! Checkout the channel for more Miata videos 👍
Great video. Very helpful. Please keep it up!
I'm glad to hear that. Thank you for the watch and comment.
Thank you for going over the different options. I bought a new ND 2 Miata 2 months ago and would like to upgrade the exhaust in the spring.
There's a lot of good exhaust choices out there for every taste. Let me know which one you end up buying.
THANK YOU! super helpful:)
I'm glad to hear it. Thanks for providing a comment and letting me know. Have you bought one, or considering one?
Great video I appreciate it man I’ll probably go with the hush o matic if it’s 17pounds or less in weight
I've heard good things about the Hush-o-matic, especially those who are looking for a quieter exhaust when the need arises.
What about the double central exhaust by ulter sport?
This was extremely helpful. Working on evaluating my options for my ND2 RF. Any chance I can get a copy of the spreadsheet? I enjoy the videos. Thanks!
I’m glad you found the video helpful 👍😁. Unfortunately I do not have the spreadsheet available. 🤷♂️
Love your Videos! Congrats! I have a question, have you ever considered the Catback Exhaust From "CorkSport"?

i think the borla muffler just sounds so perfect to my ears at least. just bought an rf this week & i want the borla
Very informative and well done, you should try using our products on your vehicle Thank you for the content
Thank you for the watch and positive feedback.

Yes, I can confirm that it will fit both the ND1 and ND2 as I had the same question prior to making my purchase, and the seller confirmed with Greddy.
Hey Chad, I’m in the market for an after market exhaust for my 2016 mx-5. Any recommendations for a dual axel back exhaust with low pitch and bass heavy sound? I’d really appreciate your feedback.
Are you looking for dual exhaust tips, or an exhaust with separate exhaust outlets?
Hey @@TheLemonFactor thanks for getting back so soon with a reply. I’ve been binge watching your videos the entire day, keep up the great work. I’m sorry for not being clear earlier, I meant an axle back exhaust with separate outlets.
Yes, I have seen some out there, but only from online pics / videos 🤷♂️
There are a couple dual exit exhausts for the ND Miata that you can find on the Rev9autosport.com website.
does all the mufflers works on the 2.0 L ND2 too?
All of these are for the ND1/ND2, model years 2016+, and specific to the 2.0L. I'm not sure that they'd fit the 1.5L, so you'd need to confirm before purchasing.
😀 lemons are bad but cars are good 🚗
Can you add baffles to any or all of these exhaust?
hi guys ! i'am from french and i own 2.0l nd. just for being sure this miata you call gt it's the 2L engine ? or 1.5?

Hello Sir good day, I just wanna ask if catback exhaust system without catalytic coverter can harm or damage the engine in the long run? Thank u
The cat helps to clean the exhaust gases coming from your car. Running without a cat should not harm your engine directly, but can indirectly cause issues with your overall vehicle performance if not done correctly.

Nope not for me. Drove one yesterday. RF version, brand new. Disappointed - very. Have now scratched that itch. Had always hoped it would be special. Very jittery, constantly moving gearstick , noisy, just too tiny inside, noisy, too much shudder on suspension, noisy, feels like its an old car, noisy, cabin quite nice but dated, noisy, nice red paint, noisy, like the 80's and no better, noisy, other than that a good car... what a disappointment... i really wanted to like it.. its just hyped beyond the reality.. and noisy if u didnt notice.....
Maybe youre gettin too old for that game, might a recomend a comfy ford explorer
Sound proofing adds WEIGHT and THICKNESS 😢 MAYBE a V6 Stang 🐎 or V6 Camaro 🐽 would do??
You mentioned the word noisy 7 times in the comment. I guess we can safely assume all sports car are not suitable for you
