Spec miata exhaust for later turbo upgrade
 

Saw this online....Spec miata exhaust | eBay

Looks good to me simple, light weight, fairly cheap. Any thoughts?
I don't see why it wouldn't make a good Na choice. And being it bolts to the factory dp I could use it in the future with a turbo dp

You'd want at least 2.5" diameter if you're upgrading over stock...especially if you plan on going turbo.

Not big enough. 3" is the only exhaust worth buying on a turbo car.

That exhaust is a joke, any N/A mod is a joke on the miata.

Your "mouth on a woman's genitals" is a joke.

I read this and then I looked left and saw Taylor Swift's mouth wide open like "BURRRNNNNN." Then the glasses came down and "deal with it" popped up. Went perfectly hand in hand with the comment.

Come on...a joke? Everybody knows you can make more power than a turbo charger with ITB's and high comp pistons.:jerkit:

Rabble rabble throttle response rabble rabble.

lol. It's going to be hard to top this av.

my miata is going to be NA for a lil while as i don't have the funds for a turbo build yet. I'm slowly sourcing all the parts. I was going to turbo my 1.6 but I'm swapping in a 1.8 insted. The exhaust i had on the car was held together with jb weld and aluminum cans so i need something to go on the new motor. I have the factory 1.8 downpipe but nothing after that.
I want something that wont need upgraded later when i add a turbo. plan to have a low boost build around 200whp...what exhaust options are out there under $500?

Enthuza.

FWIW: To flow enough to not be a restriction with a turbo, it's going to be LOUD AS FUCK on an NA car.

Honestly, just buy a stock one for next to nothing and save for a quality one for the future turbo setup.

Purchase MS instead and enjoy the marginal power increase (probs more than a 'nice' N/A exhaust might give you) with your butt dyno all while working towards your turbo system.

I was exactly where you are several years back. I thought there was a nice middle ground exhaust that could function well for both setups. Then I researched, resisted upgrading N/A stuff, did the above, and now my chi is in balance with a nice artech 3" on the way. I want you to experience this. OR do whatever you want and be pissed off later. Choose the chi.

The Mazdaspeed SM exhaust is fucking loud and not that great. The OBX cat back on ebay isn't half bad, it's 2.5" with pretty good bends. Muffler sounds good too. It's got a 4" tip but cut it off and weld on a smaller one. I've had that exhaust on my DD for at least 100k miles through snow and ice and it's still holding strong.

10x44x3" muffler

Dragracer muffler.

ok so ive come to terms with the face that whatever i purchase will need replacing when i go turbo. as i want somthing thats actually drivable and not crazy noisy.
hoping to find a good condition stock unit if not i may go with the obx system. That 4 inch pis is retarded tho

dont buy an n/a exhaust system at all. what's the point?

its a complete waste of money. Buy xidas.

well the point of buying a na exhaust for me is because driving around with nothing but a open header is verry loud...not only undbaribly annoying but also will get me pulled over allot... as of right now i have no exhaust. my freshend up 1,8 will be going into my car next weekend allong with a megasquirt. car is alreay sitting on fulll coilover system and sway bars and stainless steel frame rails and a brand new lightweight flywheel and clutch...so this isnt me trying to get more performance and wondering where to spend my money..its about a good cheap exhaust option to get by so i can drive my car again... yes i would like to go turbo but im going to tune my ms na first then go turbo when i have another large chunk of cash to blow on car parts.

buy the ebay tsundo exhaust and sell it on CR once you're done.

tsundo?

awesome that should work cheap and simple...i don't have a cat any experance on a test pipe? any one fit?

cheap test pipes on ebay as well.

yeah thats what i found...whole set up under $250 shipped.....hope it don't sound terrible. if it does that will just force me to turbo sooner i guess lol....thank you for the links

ha ha. if you got the spec miata exhaust you'd Turbo faster. it would sound like dickass.

Yep I have a Springfield SM exhaust. It is the worst freaking thing on my car. My co-driver bought it for the car so since I had no out of pocket I said lets get it on there. The absolutely most annoying thing. Drove it for a day and told him lets put the stock exhaust back on. He had already thrown it away. Took the thing to a dyno. It made a whole 2hp more at peak and that was also eliminating the cat compared to stock 160k mile Mazda exhaust. I just shook my head. We put a supertrap end (not the muffler) on it with 12 discs and its somewhat manageable to drive. Of course we lost the 2hp at peak with the supertrap. The only thing that was good about the whole experience is the 19lb lighter the car got but even that was bittersweet as it all came off of the lower rear of the car. Im still shaking my head.

And now I go and spend close to $500 shipped to get a RB header on the car since the VVT header didnt go with my 95 downpipe and my 95 header had broken a stud in the downpipe flange. I didnt want to go through the trouble of drilling the stud out or having a new flange put on the 95 downpipe so I figured why not take 3-5hp/tq across the band and get a shiny pretty header. The damn thing shows up and its freaking made in China. I feel like I should be joining a support group or something.

my header also broke 2 studs in the manafold...WHAT A FUCKING PAIN....i spent 3 hours and 4 trips to the store today getting bits drilling them out...cleaned it up with dremmel tool. looks good now..il let yal know how my ebay exhaust sounds when it comes in

It'll sound like shit, don't worry. If you have a silencer it sounds a bit better, but it's still just boomy and ricecan all day.

fan fucking tastic

no it wont; I dont steer people wrong.





It'll still work "okay" when you fit a turbo, since it's straight through and 2.25". Sure it's a cheap solution, but it's a MUCH better solution than a spec miata exhaust.

I suggested the system with THREE mufflers for a reason.
