I am thinking of getting a sports cat and have a few questions.
Given that a cat works at a specific or certain temperature range and that changing the bore size of the exhaust system changes the gas flow and back pressure and that the 33’s cat is a long distance from the heads compared to other cars.

Will any sports cat suffice or will a specific one be needed.

Thanks
Alan
