Will Flowmaster hurt too much?

Check it. Flowmasters on my blown truck had 4psi of pressure between headers and mufflers. As loud as those suckers were, I was thinking back pressure would be minimal. Not so. Magnaflows had less, but still too f'n loud. Corsa seems to be the only muffler that's able to quash exhaust noise and still flow well.
