I'm going to buy a Apexi WS2 muffler but idk what they mean by 70mm and so on. My car has a 2.25 straight pipe with stock del sol exhaust. Would anyone know which muffler I would need? here is the link to Apexi products thanks!

 

WS2 - Universal Mufflers - Exhaust

 

according to acronym finder 70mm may refer to "Micky Mouse" or "millimeter."

assuming Apexi hasn't started welding ears onto their mufflers, I would go with millimeters. 70mm translated to american is 2.75 inches. your 2.25 straight pipe is about 57mm.

 

Ok thank you very much greatly appreciate the help

 

...Old enough to drive, and does not recognize the contraction for milimeters? What the heck are they teaching in public school since I left it? 0_o

 

The problem of growing up in a area with high minorities, and a area with no white privilege.

 

Since you have a h series engine what size muffler would be best 70mm so enough pressure can be released? I only want the muffler for my future h2b build.

 

It's more of a problem of dumbass kids asking to be spoon fed all their info rather than doing some research and learning something.

 

What size is the stock Prelude exhaust piping?

 

Just...no, no. You do not get into Japanese cars and make plans for an engine swap without becoming familiar with certain fundamentals of the way the entire rest of the world measures things. Not unless you're skimming car magazines on the bookstore shelf as your sole source of information. And you're here so that isn't the case.

Also, come here and throw around "white privilege" and see how much respect it gets you. This isn't tumblr.

As for the answer to your question, I will say that there is plenty of discussion on exhaust sizes, and what you need is dependent on what your goals are and where you want your powerband to be. 70mm is plenty big for most street H22's.

 

Not really dumb kids. If you keep a community in poverty the individuals will receive education from poor teachers, poor environment, poor jobs, and people "children" etc; who have a better community ( white collar communities) will have a better environment (community), better teachers, better jobs etc. So not being spoon fed just less motivation due to social stimuli this process is a never ending circle. Yet what do I know i'm just some apparent fool.

 

That i do not know I will need to do research to find a valid answer. It should be bigger since it is a bigger engine.

 

I actually have not done any research at all for it. I just asked so I can get a answer, but thanks your right plans must be made prior to engine swaps yet I have not even started to glance at that only a existing thought in my head.
On the contrary this is a social site so it's ok for me to say that. Or should I say that "...Old enough to drive, and does not recognize the contraction for milimeters? What the heck are they teaching in public school since I left it? 0_o" as I am quoting from you is something respectable to say? Or is that a Tumblr opinion? I don't care if me saying white privilege gets me no respect, because me saying that is not disrespecting white people and if you feel offended than sorry for you being ignorant and taking that as something to feel offended by.

Thanks for your answer 2.75inches is kind of big for a 4 banger, but I will need to dp research yet I dont want to produce too much power on a H22.

 

The thing is the metric system has nothing to do with any privilege. Its the basic system of measurement used by almost the entire rest of the world...you definitely need too learn it if you intend to work on cars (unless you ONLY work on Chevy or dodge).

 

I've known how to measure since I was a child.. I've also known that on most rulers there are two sides that show inches or mm/cm. I've also known that mm stands for millimeters and cm stands for centimeters. 1000 in one meter for mm and 100 in one meter for cm. I also grew up in that same 209 area you did, and know for a fact that the toughest 'smartest' program is in the 'worst' school...so I think my point still stands....that DUMBASS (not dumb) kids would rather be spoon fed the info than do some research and figure things out on their own. I had to learn how to do all the things I know (swaps, exhaust sizing etc) pretty much on my own. The answers have already been given, it just takes a bit of work, a bit of simple googling, to figure out the answers you want.

Lastly, if you're planning on doing an H2B or whatever swap...start by getting the motor, and getting it on a stand. Don't worry about silly little things like mufflers yet. You have bigger things to research, like adapter plates, mounts, clutches etc. The muffler will come last, obviously.

 

OH THIS IS ICING ON THE CAKE:

******* REALLY? Blame society and school systems because kids are stupid but your favorite quote is this?

 

I'm not offended. And this is a tech site first and foremost, a place where people come for help when they have exhausted their google skills. Regularly there are threads posted by people who have either plainly not done basic research, or who's skills at research are so poor it's a wonder they comprehended their driver's training manual. And here you come, looking for advice on modifying an imported car, confessing your own lack of research, and you don't know the fundamentals of how the rest of the world, and an increasing amount of people in the USA measure things. On top of that, when challenged, you throw down the millennial's race-card. What else are we to see but an example of everything we fear corroding these bastions of knowledge?

 

You may say what you want and disagree with me I care less about your statements.

 

If it was a tech site you would easily have told me the answer to my question. I have nothing else to say to you.

 

We are giving you the answers. We are just making you work a bit for them and making you learn a bit along the way.

Don't throw the huurrr duurrrr "I didn't learn in school gimme gimme" and expect us to feel sorry and spoon feed you.

You're never too old to learn something new. It is also better to remove all doubt by finding out for yourself the truth, rather than trusting somebody told you the right info and it be wrong and costing you.
