yes, but the idea was based off of true street,

technology changes, mufflers for a street car hasn't

NMRA True Street
POWER ADDERS & POWERTRAIN
Any Ford-based engine, and any number and/or type of power adders are permitted. Any manual or automatic transmission is permitted. Any rear end is permitted. Exhaust system with mufflers is required.

True street rules are pretty simple

DOT's,
No Back Halved cars
Any power adder(s)
Run it through mufflers
