In preparation to recycle an S2000 muffler onto my Accord...


Morbid curiosity [that and an angle grinder] got the best of me and I decided to open up the "leftover" S2000 muffler. The results:

Three sections. Middle section is completely sealed. The middle section is some resonance chamber that the two side tubes are pleated and can pass exhaust through.


TRIPLE Wall Stainless Steel... and I thought I was anal.



My question is... How in the hell can someone NOT make power when swapping out these mufflers? I can definitely see how this exhaust is quiet (hence the reason for going on the Accord)... but this has got to rob power??? I can see how Honda flared the inner tubes on the insides of the muffler to minimize loss... but this would not be my first choice to make some decent power.

But then again... what do I know?

 

I think honda chose to not soundproof the undercarriage and instead overly deadened the exhaust by designing a multiple resonator/muffler/silencer layout.

But yet most of the dual aftermarket exhausts don't seem to make that much more power.

 

did somebody say soju?

 

Accord exhausts don't make much more power either?

 

interesting... i doubt we will see rusted s2000 exhausts in the near future

 

A quality exhaust that will last and deadens noise to an acceptable level. Thanks for sharing.

 

Well, first remember that there are TWO of those canisters, so right off the bat it's only half as restrictive as it looks.

The "straight-thru" (passenger-side) canister might also be a little less restrictive; we don't know since you didn't cut that one open.

We do know Honda went through many many exhaust designs looking for something that was reasonably quiet without being lossy. (There's a photo in Dan Carney's "S2000" book of a huge stack of prototype exhausts that were ultimately rejected.) Looks like they achieved this, as thetz noted, at least partly by using heavily insulated dual canisters, albeit at the expense of high weight.
