Is that a good thing?
I've never experienced a vehicle which performed without the back-pressure of the rest of the exhaust system.
The entire system was 'tuned' as a unit.
If 'reversion' happened to occur within the system, it would manifest itself as a 'bluing' along some point in the exhaust pipe. Simply cutting the pipe at that point of discoloration constituted 'tuning', and elimination of any 'reversion.'
One might notice that General Motors' highest-performance Corvette engine closes off half of it's exhaust system during cylinder-deactivation in order to 'protect' back-pressure for the half of the cylinders still firing!
Is this 'Unicorn Corral' material?
