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.

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.

yeah, maybe if i had the exact numbers memorized. Just as easy for others to click a damn link and view things for themselves, especially when they are wanting the info.

i just dont see why people complain when help is given.... how many damn threads do you people click a day? one more isnt too bad to find your answer. period.

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.

I never said it was my question. And most would assume if the question was asked in inches then it should be answered that way. Just trying to help the guy find his OEM pipe size while you appear to be wasting my time.

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...

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!

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.
