Roadster Sport Exhaust on ND Miata - Review and Install!!!

Goodwin Racing's glorious street muffler for the ND with Hemholtz chamber. In this video I remove the stock muffler and install this one. Video comparison with sounds of revving. Also in-car and outside car footage.

[@dlg5485]

Sounds fantastic! This exhaust will almost certainly be going on my ND3. I've listened to over a dozen exhausts for the Miata, but the SuperStreet remains at the top of my list.

[@wwilliams1358]

Your smile at WOT...almost says it all. Almost, because as you said, there is always, and I mean always, the Wife test! Thanks for the video!

[@d1gw33d]

Thank you for the in cabin test. Greatly appreciated. Most just give you audio right over the exhaust.

[@zoomnpa9905]

Video is well done. Makes me want that muffler! Thank you for your time and effort on the video.

[@stephen2215]

Can't wait to get one. Your smile sells it!

[@14981fc]

Thanks for the video, you've made up my mind about this axle back, the sound is perfect! How to shipped it to Vancouver BC without getting robbed by the custom and brokerage is another story though.

[@Trigger-xw9gq]

Agreed. I just got dinged $75.00 with all the taxes and brokerage fees on an order from out of the country. Surely there must be some good mufflers for the MX-5 within Canada?

[@lupecruz4564]

Just ordered mine! Great video!!

[@zzrsteve7934]

Very nice video. I'm strongly leaning to this exhaust for my 2023. Thanks.

[@stevem9766]

Have you gotten your new exhaust yet ? I just purchased a 2023 MX-5 RF manual myself . And I’m looking at doing the same . If you got it ? Do you like it ?

[@zzrsteve7934]

I do have it but it took forever to get a new gasket delivered (probably don't need it but just in case) and now it's cold as hell so it's sitting in it's box still. When it warms up again I'll slap it on.

[@inclusivelove5165]

My next dream car.

[@Erkkremlinklum]

Man that sounds great

[@TheScuballoyd]

Your smile says it all.

[@Koishishibaman]

That sounds very good. Had 3 na miatas with intake, headers, high flow cat, and rb exhaust. Great sound! Like the race version also.

[@johns.9466]

Great video -- very well done -- Thank you!! I am considering adding one to a 2022 Miata RF. Are you still happy with this RoadsterSport SuperStreet 15 months later? Thank you again!

[@DarkstarDarth]

I intalled it last week on my ND1, you control the sound by how much beans you feed it. Turns heads everywhere you go. Adds a little more HP on the top end.

[@ericmccolough2482]

Good video and yes it sounds great, so there's zero drone with the roof up?

[@EG6chris]

I just installed this last night. It's crazy how WOT sounds EXACTLY like this video. Great sound, but it's a bit loud for me when driving around town. Going to put the baffle back in until the muffler breaks in a little more.

[@gustavette8487]

Does the baffle really make a significant difference?

[@NDEEZMiata]

@@gustavette8487the included cone baffle cuts the booming sound on decel around 20% as well as reduces the overall volume a bit. Cold starts aren’t quite as loud either It’s not a huge change, but it’s enough to take it from this is slightly loud/annoying to just right. There’s other baffle options as well, haven’t tried them yet The downside is it doesn’t sound quite as good. Great option for daily driving though. Mine has definitely mellowed out with some miles to the point I don’t really see the need for the baffle unless I was going to do a lot of top up highway driving. IE road-trip or hour + drive

[@oceanpointedistributorscor4051]

@@NDEEZMiata Thanks for your complete info!

[@opmike343]

It's all steel construction with no fiber baffling or packing materials. There's nothing to "break in."

[@Post_Leako]

That high pitched noise when you went WOT and presumably at redline, was that just the microphone being overwhelmed or was that drone? Does it drone?

[@toolloots]

Put mine on today. Absolutely love it. Thanks for the vid.

[@Icefirenice]

Is this the super Q?

[@toolloots]

@@Icefirenice just realized his is the Super Q. I put on the RoadsterSport Race.

[@ramirof1986]

@@toolloots how can you tell..looks different from it. Looks exactly like the Super Street.

[@dougmaverick3287]

Is the Goodwin racing race Muffler much louder than this one? This sounds pretty good. I think this sounds a little deeper than the race.

[@richard-mai]

Since the exhaust takes up less space underneath, is the underside aerodynamically affected? Does it create any stability issues at higher speeds? I watched a video of someone installing a Verus rear diffuser and claims it helps with the above issues due to smaller exhausts

[@fartbus]

This isn't a McLaren lolol. But to answer your question, no I have not noticed any aero or stability issues. Car feels great.

[@PixelGamesification]

unless your tracking your miata alot, constantly hitting 90mph+, and are absolutely concerned with speed, you won't need to worry. Diffusers are meant to reduce the drag that the rear underbody has when it has uneven spaces, and are usually used with the full underbody as a way to achieve maximum speed with minimum drag. A small exhaust change won't affect it at all if you are just daily driving the car on the streets.

[@pchae1]

I've read that some people's rears lift and ride on the 2 front wheels when going 80+ mph (thankfully not kilometers). With the Verus front splitter, you might be able to achieve 4 wheel lift like a hovercar.

[@GJJC13]

NIce video, ... where was the mic located while shooting this video?

[@vincentsoo1634]

How about with the top up? Did you also ever try the baffle?

[@Aye_chillaxe]

@Jeebus Hiii, I bought one not long ago, it didnt came with a gasket so I assume I wasnt supposed to install it with one but I noticed that it was leaking condensation from the connector so I assume its a exhaust leak. Is that normal ?

[@avotius]

In the mail arriving tomorrow!

[@josepacheco154]

How long did shipping take? Thinking about getting this exhaust

[@stevechance150]

5:32 GOD DAMN!! Did you catch second gear?! I may have to rethink my view on Miata. And that exhaust sounds SWEET!

[@dlg5485]

Anyone who views the Miata as anything but the perfect overall sports car, simply hasn't experienced one. There's a reason Miata owners say... M iata I s A lways T he A nswer

[@gustavette8487]

Sounds great. Do you know if this same muffler, but the race version (also with the Helmholtz, but no small resonator before the tip) is much louder?

[@pschaefer143]

The race muffler is most definitely louder. You get a bit of a tone difference but it's extremely loud

[@jorianmillyard3257]

Hi great video, can you please tell me is this on a 1.5 or 2L and looking at the Goodwin site which roadster Odell is this exhaust is it…super q, rashes, or superstreet? Thinking its the superstreet.

[@benkerley1014]

There are no 1.5 NDs sold in the US.

[@potatomafia4407]

Sounds great! Did it pass the wife test?

[@fartbus]

She was good with it! Just below her annoyance threshold

[@BN99239]

I see water coming out of the area where you attached the muffler around 2:41. Is that a problem?

[@justchillin619]

how's the drone with the top down?

[@Krazertv]

Just curious, did this ever pass the wife test?

[@curtfox91]

How tall are you? Looking to get an ND2 im 5ft10 or 11 long legs

[@fartbus]

6'3. I fit but just barely. Was too tall for the RF.

[@curtfox91]

@@fartbus thanks for the Reply looking to get a Soft top and the Same exhaust. The only exhaust i found that has a great tone but not obnoxious when cruising

[@kgm5330]

6’1”, 200 lbs (90 kg) have ND2 2020 RF GT. It was quite a change from NC2 to ND2! Seemed snug at first, but after a couple thousand miles, it seems to fit perfectly. I now prefer it to other options - what initially felt snug now feels like it was designed to fit around my body. I have longer legs, and that is the part that is pushing the limits for me. I have plenty of room elsewhere. My helmet (very) easily bumps the ceiling, but not enough to be a significant issue. At 5’11”, you will be convinced that RF or ST was made just for you! But it might seem tight when you first get in.

[@gigi9467]

6”1’ 195 pounds long torso i fit fine but need to lower my seats to fit with a helmet

[@DA_Buddha]

Super late to the party but whatever. Drove an RF a couple years ago with the top up if memory serves correct. I'm 6ft 180lbs with most of my height being in my legs so I was more concerned about leg room when driving and if there was enough room for my knees and such. Needless to say the addition of the telescoping steering wheel definitely helps.

[@jull444]

Is this ND1 or ND2?

[@jackanderson2773]

ND2 here . Not sure about his . This axle back should work on an ND2 .

[@curtissullivan5441]

ND2

[@pupete01]

Aaron Rogers??? 😀

[@Laz_Arus]

I know I'm a little late viewing this, but I'm surprised no one picked you up on the spelling and pronunciation of the physics this muffler is based upon. It is spelled heLmholtz.

[@wasimgotauzi1922]

Sounds almost like a s2000

[@dareeltoro6681]

To much drone, I pass

[@fabalberico9620]

Great video - very accurate sound comparison. @rjbean13 this is the one I have, and I’m 100% happy with it.
