SO, anybody know if I can stand up the mufflers, and flush then out with a degreaser? Not sure what's inside these titanium mufflers, and if I would cause more damage by doing this...
This has all been a painful process, so hoping for hopes sake someone out there has advise, or experience...
Thanks!!!!

The core of the converter is a fragile ceramic honeycomb coated with a microscopic layer of precious metals (like platinum, palladium, and rhodium). Strong alkaline or acidic degreasers can strip these precious metals, react chemically to degrade the catalyst, or leave behind damaging chemical residues. While some forum discussions suggest DIY methods like soaking an extracted converter in mild soap or degreaser, professional mechanics and manufacturers generally advise against it.
Consider these factors before cleaning:
Catalyst Contamination: Strong chemical degreasers can physically "poison" or alter the catalytic coating, rendering the converter useless.
Damage to the Substrate: The ceramic honeycomb is porous and fragile; high-pressure soaking or using highly corrosive chemicals can break apart the core, causing it to clog or rattle.
Alternative "On-Car" Cleaning: Instead of pouring degreasers directly through the exhaust, many professionals recommend driving the vehicle at higher RPMs (e.g., 3,000 to 3,500 for 20-30 minutes) to allow intense exhaust heat to naturally burn off carbon buildup.
Chemical Additives: If you want to clear mild contamination without dismantling the exhaust, you can run a specialized catalytic converter cleaner (like those from CRC Industries) through your fuel tank.
