Posted on Classified I'm looking to swap my black Granturismo Sport Oval back boxes with a pair of 4.7 Granturismo Auto twin pipe back boxes. Emblem will do the work 50/50

Surely there is no difference. The quads are 2 pipe outlets and the ovals are the same aren't they? The only difference is with the early non valved boxes isn't it?

There is a noticeable difference in sound plus the exits from the box are different.
