2006 RAV4 6-cylinder: A Toyota replacement muffler is only sold as a unit made up of the muffler, the catalytic converter, and the connecting pipe; all configured as a fixed unit, i.E. Welded, no clamps joining the parts. Dealer price is $1,195 for the part + labor. Question: is there something unique about the Toyota muffler that makes it proprietary to function as an integral part of the catalytic converter/exhaust system? There is no external sign that the cat converter itself is compromised. I could have a muffler shop physically cut out the bad muffler and replace it for MUCH less $$ but does Toyota's extreme pricing indicate that an aftermarket muffler might not properly work with the cat system? Thank you.
