Is there any difference between GT take offs and aftermarket mufflers like dynomax..etc. with regards to restrictive flow, sound n performance? I am planning to upgrade my mufflers on my 07 V6 stang. Also are there aftermarket mufflers that are just easy bolt ons without the need for cutting n welding? thanks a lot n hoping for your kindest inputs..

While the GT mufflers do flow pretty well, most of the aftermarket ones have better CFM numbers. They're all direct bolt in with no cutting/welding required.
