What is the difference between the header back and cat back performance exhaust systems? What a header back exhaust?
What is a cat-back exhaust system?
What a performance exhaust system is it?
What are the best noise performance (so far the best I know are turbo muffler fiberglass packing)
A header replaces the exhaust manifold and cat-back system replaces the entire exhaust system after the catalytic converter.
Regarding what is the best system, which depends on how you judge them (an important criterion for many people is how it sounds and it's a subjective call).
