When the car goes from 8 cylinders to 4, it goes from sounding like a V8 to sounding more like a 4 cylinder car -- thus, the exhaust tuning becomes even more important.

Early on, the aftermarket companies that are developing performance exhaust systems found that they have to be very careful in their tuning -- because if you don't it kinda sounds like the car is 'burping' when it goes from 4 to 8 and back to 4.......

(...not to be confused with the burping they make after a meal of 'smoked mustang'...) (sorry - couldn't resist that last remark...)
