Largely, this exhaust is pretty terrible. The resonator sounds like it's full of rocks; the muffler rings, has no packing, and has thin walls. It also sounds pretty terrible as-is.That said, 2 stars instead of 1 as I had low expectations, and was planning to cut out the resonator and muffler from the get-go. The exhaust pipe, hangar locations, flanges, etc, all do match up and fit the car well (95 Miata, with rear subframe brace).If you're needing a starting point to build your own thing, this exhaust works.If you're running it as-is, I'd avoid.

This exhaust only lasted about a month and a half before something in the muffler broke loose and started rattling really badly. The fitment is a little off and potentially hits the axle on the drivers side creating a banging noise when the axle turns. I had to wire it down to clear. Very tinny sounding under higher RPMs and drones like crazy at freeway speeds of 65mph. Do yourself a favor and buy a quality exhaust you'll be happier.

I had this exhaust on knowing it was cheap, and it was my downfall. A hanger broke off and my miata now sounds like a freight train thats coming off the tracks. It was expected, so I’m still gonna rate it 3 stars but it only lasted about a month and a half before it started making godawful metal rattling sounds.

Muffler cassé, (brisé en dedans) qui fait un son vraiment « cacanne » et aucun service du vendeur, contacté par email et ne veut pas un retour ou remboursement de l’article! Je ne recommande pas. Mauvais service et article de mauvaise qualitér

It fit really well when installing but that's the only positive thing about it. The metal is so thin and weak it didn't even last 2 weeks on my car it started blowing holes in it. The inside of the muffler was loose and made a rattling noise, and overall the tone of the exhaust was terrible and loud. Didn't expect much from such a cheap exhaust but this isn't worth the money at all.

didn’t line up properly, and even after that, the inside of the muffler came loose so without curing and rewelding it sounded as if I was dragging chain link fence

Does not fit properly. A section of the exhaust fully made contact with an axle flange (i DO have the stock 1.6 diff. and axles). So loud and not the good kind. With a header this sounds worse than a fart-canned civic. I'm just gonna buy a borla like I should have.

Sounds good and looks even better! Took a little work to get it to clear the rear axle, couple smacks with the hammer fixed the clearance issue, worst part was just having to take it all back off again so it wouldn't rub that axle. Will update on longevity but very satisfied with how much deeper this sounds! Feels like I might have a little more torque too *update 4ish mo later it has started to disintegrate. Not recommended.

Went on in 30 minutes. Great deal for the money. Not a borla or magnaflow and really raspy and loud but for the money a great deal

Allignment with stock hangers was pretty close. Not a perfect fit, but good enough. Installed it on my 91 Miata at the same time as an ebay 4-2-1 $79 header. Only original part of the exhaust system left is the cat. This dna exhausted bolted to the cat perfectly which is more than I can say for the eBay header for sure. It's super quiet at idle up till about 4k where it starts to get loud, raspy, and maybe Abit rattely. Again at this price {106 on warehouse deals) it is perfect so far. Other big bonus is it weighs about 40 lbs less than the stock exhaust and muffler. I'll try and update with how it holds up.
