I'm 87% sure it's 2.25

 

i think it might be 2.0". Because the The Megan Racing Midpipe is 2.25" and when i installed it, the Megan Racing Midpipe looked bigger than stock.

 

Thanks guys...anyone else??

 

Yikes at 2". Power to be had, power to be had.

 

This is from my Mugen exhaust thread i posted a while back.

OEM measurments are inside. :thumb:

^ why not just say what it is. i dont want to search another thread.

 

damn you beat me too it lol

 

How is it "searching another thread"? lmfao- numbers are right in the first post. why should i open it up, grab the exact numbers again, copy and paste them for you?? dont be so lazy.

i didnt realize clicking another thread and viewing it was such a pain. hmm i wonder how you all feel about "searching" to find other information you wanna know about....

sorry, spoon feeding isnt something i do often for others. sheesh, try helping others out just a lil bit and its not appreciated. lmao

were just saying it would probably have been easier just to type in a few numbers rather than all of that.

 

Funny after all that i still dont know OEM pipe size in inches which is what the ORIGINAL question was about. hsnap:

 

wow!

one: it was never "your" question

two: where in the OP does it state to answer specifically in inches?

three: learn to convert mm--> inches

if your not capable of doing that...i feel sorry for you.


that is all. have a nice day.

OEM is 50mm diameter, or 2 inches.

 

It would've taken half as much time to type the info from that thread instead of searching for that thread, then making the link...

 

wow 2" seems a little small, that's about what my 99 gsr has and its a smaller engine with much less hp.

 

Guys, lets not bicker...we're not 12 (well maybe some of us are close, i'm not). Thanks for the information from the poster who included the link and the person who broke it down into inches! That's all!

 

100% sure its 2in i just had mine took off for my 2.5pipe

 

Is the Civic SI OEM cat back 2.25 or 2.5?? Thanks!

2nd: wow!

Sean, He never said it was his question.

And he's not a moron and if metric that would be a +/-.090 pipe..about the size of your....nevermind.

And I feel sorry for you for a non-constructive answer. Means you have nothing of value to add.

I kind of wanted to know the answer as well since I'm looking at Vibrant Street exhaust.

Have a lousy day.

 

People in this thread need to not be. In this thread.

 

First off THANKYOU!!! HalfNHalf83 for offering the very useful information. I was able to find it useful because I, unlike some people, know how to click on a link and read and I am able to convert millimeters to inches.

Life Lesson:
When someone helps you people then you should learn to appreciate it, especially when they are helping you for free. And especially since it is free then you shouldn't expect them to do everything for you. HalfNHalf83 provided more than enough information so the very least you can do is use your high school education to read and convert a measurement system.
