does anyone happen to know the id(inches in diameter) of the stock exhaust piping?

tried finding it but couldnt.....

will_rex

I believe it's around 2 inches.

i believe all hondas stock piping is 2 inch.
if not, its 2 and a quarter.

ggutier

if someone asked you for the pipe's id, i believe that is inner diameter. (od would be outer diameter)

the muffler section is 2.25. search for "measurements on 2006 2007 si muffler". has all the specs.

Well give us some idea of what you want, I bet we can figure something out.

I recommend full stainless steel with a resonator along with the muffler. But then you can think of brands and stuff.

cashdealer07

any recomended brands?

Just to confirm what ggutier said above, 'ID' is in fact inner diameter, and 'OD' is outer diameter. However, when referring to pipe measurements, typically the diameter listed will be the ID. For example, say i ordered 2" schedule 40 pipe. 2" would be ID (inner diameter) and schedule 40 is the wall thickness (.154"). A piece of pipe this size would have an OD (outer diameter) of 2.308" (add the wall thickness twice for both sides).

Thats probably way more information than anyone wanted to hear, but I'm extremely bored here at work. And just in case you were wondering, I sell metal.

Oh wow buddy, who's trying to sell you stock Si exhaust for 700 bucks? They are seriously trying to rip you off with that deal.

On the side note that Muffler from the Si does fit with ex, just not the whole thing.
