I got advice for a glasspack after the convertor, then a muffler, and I melted the innards of the glasspack. The restriction was just right, but it did not hold up. I exploded 3 factory versions, they are much too small, and hotter than a convertor! I may have even aided and abedded a complete belly pan failure with resonator. OE and 3 main boxers have been torture together as usual. My exhaust is simply 2 inch, straight midpipe, factory y-pipe with convertor and dynomax full chambered muffler. It is great right now, and passes inspections, but bad fuel and cold engine..there is a hint of a spuutering sputter in engine braking, I want it to go away forever.
I am guessing the honda category with the less than 2 liter engines have this same phenomona. they made a resonator universal and throw it at the market, never accounting for very very hot tiny stroke engines. I did find stainless steel, but it is not honeycomed, it is straight through. the straight through leaves a bassy rumble in the interior of my very hardened welded sube.
An acoustic mystery, as well as chemistry and heat to withstand oe convertor not far off...

Any suggestions on a real resonator to match a sube at 2 inch? non-straight through? restrictions are a must avoid..while going for cadillac silence..
Searches on web for hacked up echaust is like finding a mr.gasket plenum that bolted up to an 87 sube..it is never the front page of ebay ya know?
I've never heard of a Honda with this problem, but something I've done on small engines to use as a resonator is to gut the cat from a larger engine, and just place it inline after your OEM cat.

This allows the exhaust gasses to expand and helps to silence them.
