How Muffler piping is measured
"...due to its superior design and function of the pre-formed band that allows the use of O.D. components (exhaust pipe) to I.D. components (muffler)."
I'm thinking about using a band clamp and ran across the above statement. Is this true for mufflers? I know the b-pipe piping is measured in OD, but this is the first time hearing that the muffler pipe would be measured in ID.

Hondas traditionally used flanged connections between exhaust sections, so it doesn't matter about OD vs. ID.
Lotsa other cars have lap joints where there's an expanded & slit section that's just big enough ID to slide over the OD of the prior section. That's for all pieces, not different for pipes vs. mufflers.

I have custom piping, and considering using a band clamp so I can swap out different universal exhausts until I find what I want, or rather, what I can deal with. The quoted statement was something that was describing why these band clamps were good.

I just got my muffler, and you are correct. The inner diameter at the ends of the piping on the muffler are 2.5" I wasn't sure if 2.5" inlet/outlet on my muffler meant inner or outer diameter, and now I know it's both. The ends where it meets the other exhaust piping has been expanded slightly, creating a 2.5" ID.

Re: How Muffler piping is measured (Takumi Fujiwara)
Maybe the advantage they're trying to sell is being able to remove & reinstall that stuff. Normally with those lap joints, a normal clamp deforms the overlapped section, making it very difficult to take apart. But you need to swap parts a few times until you figure out what you need. Maybe don't clamp them very tightly, so they'll come apart OK. They'll probably leak until you settle on a system & tighten it properly.
Or check out those clamps in more detail. I don't really know about them except I can guess. Maybe you have to cut off the expanded section, prepare each end whatever way is required for those clamps? Then you can unclamp them, swap pieces & reassemble without damage. It sort of reminds me of GrayLoc flanges but those are for high-pressure piping.

Re: How Muffler piping is measured (JimBlake)
The part that sold me about the band clamp I bought was the fact that it's "pre-formed" Half of the clamp is 2.5" ID while the other is 2.5" OD, accomodating the diameters of both the loop over axle piping and the "lap-joint" on the muffler...
It should be going on my car as soon as hytech sends me the stuff I ordered.
btw, what is the best way to cut exhaust piping anyway? I know I can use a cheap hand saw, but what is the best way to make sure it's cut perfectly flat/straight? I'll end up sanding the cut area... but I can get **** at times.

But it's got 3 or 4 wheels instead of 1, it's bigger & stronger, & I don't own one so I don't know how good it works.
