Why break in a catalytic converter?
Just as new piston rings need to be broken in and seated to the cylinder walls and flat-tappet camshafts need to be broken in with their lifters, a new catalytic converter also requires a break-in period to provide the expected service life and efficiency. The issue deals with the required expansion of the converter matting that holds the substrate in place.
How does a chambered muffler work?
Chambered mufflers feature a series of internal chambers and/or baffles. As the exhaust pulse enters the muffler, the sound waves bounce and reflect through and off these walls or cavities, causing the sound waves to bounce against each other. These sound waves cancel each other out, which reduces noise. Each muffler manufacturer follows its own design in achieving this. Essentially, chambered mufflers use sound-canceling technology to reduce noise while producing a desired sound level and exhaust note tone, with varying designs that appeal to stock replacement or high-performance sound attributes.
