Anyone know of a great aftermarket exhaust? I saw the Remus video but i just can't bring myself to pay the $700 for it based on such a short YouTube video. Don't want my car to sound ricey.
This is my first Mazda and not sure whether they even sound good with exhaust or not. ??

I’m not a big lover of playing with exhaust systems. The design is now so linked to the performance, economy and emissions that altering the through flow is probably enough to upset the whole lot. We’re all a bit different but having spent years developing vehicles under very controlled conditions has taught me a thing or two about the effort that goes in to make these things street legal. It seems a shame to just undo it in one stroke......

.......and to make it noisy? I don’t get it.

Have a read...........

I'm on the fence on this one. On one side, I completely agree with Anchorman on exhaust flow changes. In addition, I personally believe an exhaust note sounds much better coupled with a manual transmission and the US currently only has the automatic available.

On the other side, I replaced the my manual transmission Miata's' exhaust header, mid-pipe and exhaust with Roadstersport products specifically designed for the MX5. I absolutely love the sound of that car and have received many compliments on how it sounds sporty, without being ricey or loud as the note is about 20 percent louder than stock. In addition the improved flow added about 10 HP based on my butt dyno.

Personally I will wait and see with the aftermarket brings. A couple of weeks ago I spoke with people at Racingbeat and they recently obtained a CX3 for aftermarket product development. They indicated one of the first products they will pursue will be an exhaust.

If there was one thing I learned from my past cars is to have a goal in mind. Depending on where you want your cx-3 to be whether you are pursuing performance or just styling or even just sound differences, be prepared to give something up for each mod you install as silly as it sounds. Anchorman is correct and with something as electronically precise as this, I personally would suggest holding off on 'performance mods' since it most likely will effect the efficiency and flow in a negative manner.

Although, regarding power, I would probably suggest against that since making "big power" would be almost impossible with the current engine build and ecu programming. I learned that the hardway on my last car as you can build up the bottom end of a block, have all conditions perfect, fuel system exactly where you want it, to get a big NO in your face when faced with tuning options with emissions since it will never pass and you would have to revert everything back to stock. But thats just my 2cents.

I changed the exhaust on my WRX (catback exhaust) and was told that it wouldn't adversely affect anything or void warranty. I never considered extensive mods that affect warranty or reliably.
So I never really thought an axle-back exhaust would negatively affect a Mazda.
My previous car was a fiat Abarth which comes stock without mufflers. it had an awesome sound, so that's why I would consider a slightly louder exhaust on the Mazda.

Why is everyone on this forum against doing any mods to the cx-3????

I would like to see multiple mods done to my cx-3. I'm going crazy because there is no aftermarket parts for this car!
Someone please remove the second cat and do a muffler delete so we can hear what these cars should sound like>:)

Im all for mods, another thread I started was about getting information regarding available mods. It's just too good looking and sporty not to take it a step further.

I too am looking for an exhaust for the CX3. She sings so nicely when she revs, give her a proper microphone, and she'll turn heads. The Remus ones, judging from the very short, and frankly useless video, doesn't sound all that impressive, plus the costs aren't worth it. Also, from research, there won't be much we can do regarding exhausts systems starting from the headers, being that they are weirdly shaped and specifically designed for the skyactiv motors. But something like a catback or axleback will do fine.

I can just kind of imagine it in my head, revving to 4k or so, slowing down, the down shifting, hearing it rev high again, all with an aftermarket exhaust ... excuse me a second

Blimey. You sound happy before you've got it. I hope it sounds just how you margined when you get it!

I have a "slight" infatuation with bringing cars to life with a well matched exhaust. I had a Jetta MK3 VR6 with a 2.5" exhaust that sounded like heaven, add the sound of the supercharger ... oh I miss that one dearly.

I have to agree with anchorman and Cuzlarry about leaving the exhaust alone. I purchased a Mazdaspeed axle-back muffler for my P5 when I bought the car a dozen years ago. Changed the exhaust note a lot and seemed to provide more zip in acceleration, but the constant drone from the muffler got to be annoying. Being a chromed or polished piece of equipment, it was swapped out for the stock muffler for the winter, as I didn't want the snow and salt messing up the looks of the muffler. Nevertheless, I changed it out in the spring and fall for a few seasons but it sat on a shelf in my garage for the past few years. Maybe my not being 20 or 30 years of age has something to do with it.... All I'm waiting for now is a K&N air filter.....

I tried a K&N filter in a RAV once. Never again. All I could hear was the intake sucking and being a diesel it sounded like I was constantly being shadowed by a Phantom jet.

I'll show you some diesel photos and pdf's later this week but they make enough strange noises as it is without introducing any more.

Mine will be staying exacty as built unles they come out with something to make it quieter!

I have a 1990 Miata with its original exhaust, which has opened up a bit over the decades, and it sounds pretty good, of course with plenty of drone at high speeds.

But my '12 Corvette, which came from the factory already set for the track with the proper suspension, dry oil sump, brakes and tires, has a Borla ATAK axle-back exhaust I had installed.

It did not alter the performance at all.

If you stay with axle-back or even cat-back setups, you will not harm the performance of the CX-3.

Just my 2 cents.

You may well be right but if you consider that the whole “Skyactive” concept revolves around the construction and tuning of an engine to meet the latest emission standards from around the world, you may well interfere with that aspect of the vehicle. In the UK, we have an annual test during which, probes are inserted into the exhaust to measure the emissions and they are periodically tightened to meet new legislation.

Its up to the individual if they want to change it but all I would say is, if you have to have the emissions tested at some stage, you might struggle unless you can find an expert to make compensation adjustments to the engine mapping.

I’m not a tree hugger by any stretch of the imagination but I do believe that all this climate change stuff that our big bosses are attending in Paris has got to bring some change. Our obsession with motors is ruining the world and the sooner internal combustion engines are gone the better. I’m quite happy to subscribe to the clean air thing and if I’m brutally honest, I think that noise is all part of it and silent electric vehicles are heaven to my cranky old ears. Its pretty well known that I’m up for exploring how these CX-3s come apart but my exhaust will not be tampered with!

seeing how general consensus is that most seem to hate the idea of an axleback exhaust upgrade, I won't hold my breath on great answers on this thread as to my original question of whether anyone knew of any other good exhaust options on top of Remus for the CX-3 at the moment. :p

There isn't, not yet anyway. Other than the Remus one. Ive been keeping my eye out on aftermarket parts, and other than the intake I ordered from Corksport, there isnt really anything for the CX3 yet. Itll come though, Corksport have their hands on a CX3, expect them to start throwing up mods for it.

Racingbeat, a Mazda performance part specialist, recently bought a CX3 for aftermarket part development. Checkout their website and give them a call.

Over the past decade I have been suckered into purchasing many bolt on parts for my previous vehicles (S2000, RX-7 and RX-8) - and coming from this I can guarantee that any cat-back (especially axle back) provide minimal gains, at best.

All you get is sound, and a fancy exhaust tip. If that's what you're going for, then go for it.

For any substantial gains to be worth your while (and voiding your brand new factory warranty) you would need to swap in from header, get a high-flow cat which will undoubtedly f*ck up the fuel economy and the whole purpose behind skyactiv. Finally you would need to upgrade your intake and tune your ECU to learn the new upgrades. I did exactly this on my 2001 S2000 and net an increase of 28HP to the wheels @ peak powerband, and I was out roughly $5k after parts and labour. Not worthwhile IMHo.
