My model of MX-5 is: __Mk.3.5 2.0L Sport I’m based near: __Hull I’m looking for technical help or recommendations on: __Stainless back box Anyone using a gravity performance back box? What is it like for noise etc? [image] Exhaust Back Box - Mazda MX5 MK3 NC 1.8 2.0 06-15 | Gravity Per…

I can’t help on the video front, but I was behind Dean’s car for about 30 mins on a Club run the other month and it sounded good! :blush: As said, a bit louder than stock and a slightly deeper tone. I’d be happy with one on an NC certainly.

Don’t have a video but I do have neighbours who seem to think they are the noise police. They hate my motorbike even though it has a fully E marked exhaust on it. So far there hasn’t been one squeek about the MX5 exhaust.

Got one fitted to my NC, can’t say I’ve noticed any real difference in the sound during normal driving although I suspect that’ll change when I get round to fitting the gravity performance de-cat pipe I’ve got sitting in the garage. It also looks nicer than the stock backbox.

They have just given up on you! Trouble is the car starts on a digital choke set at 2k in my case.

It’s probably not as well made and may not last as long.but, if it produces the same result but for a shorter length of time t…

Well that’s what I did…buy a stock one from MX5 city for £140 or spend 60 more on a stainless Mk3/3.5/3.75 Exhaust Rear Back Box Silencer

I hope that works out. My NC already gets grief for being bloated. Adding a heavier than OEM exhaust is just adding fuel to the flames!

Out of interest was this a replacement for the original standard exhaust? It looks the same and is an excellent price. I’m not disappointed by the original silencer on my NC. I’ve got a posh IlMotorsport jobby that I swap out every now and again. I like it but it’s a bit noisy. Swapping between the …
