What to do for lt1 restrictor plates?

[Fbody383]

6.24.3 Any suitable exhaust system may be used after the manifolds (or headers on cars that are
allowed headers). The exhaust must exit behind the driver and be directed away from the car.
Mufflers may be required to meet sound regulations depending on track location.

It's in there...

As I understand the intent of HP/TQ rule, one would declare (as I do) that there is an exhaust restrictor. Certainly I can change that but gain the risk of being non compliant, and non compliant on purpose gets too close to trying to circumvent the rule, or cheat, if you will.
