I hope your talking about straight "through" magnaflow mufflers. When it comes down to a stock/lightly modified L98/Lb9...etc You are not going to gain a ton of horsepower between systems if they are both chambered.

Yup. Flowmaster has that sound that seemingly no other exhaust can produce and there will be no power difference on a stock or mild car. Even on decently built cars the difference is minimal. Choose whichever sound you like better.

Magnaflow baby! Straight-thru design for extremely low backpressure. You can look clear through it. Quieter than a Flow at idle and at part throttle, you can hear the stereo and talk to your passengers without yelling. And they're loudern'hell at WOT. Actually they start getting loud above about 2500 rpm.
Maggies sound totally different than Flows. Name your poison.
