You actually WANT some CSA reduction the further from the motor you get.
That's because the exhaust gasses cool and become more dense. They also slow down because of this. If you maintain the cross section the whole way, you'll actually have more back pressure.
Ideally, you wouldn't lose any of the exhaust heat, and that's one reason why ceramic coating and wrapping are used.
