Best flowing?

Flowmaster 40's? Hookers? dynomax ultra welded?

Currently I have dynomax street legal mufflers on the car.

For a 70-71 challenger 383 car that might be too slow for Stock eliminator in the NHRA and has everything else that pure stock requires....ie stock valve springs, stock 4 wheel drums and with a cam change, a fuel pump, water pump would be good to go!
