What is the difference between the muffler on a QP GTS Oval tips and the equivalent on a Granturismo with oval tips?
Is it that they are identical except for the longer pipes to the tips?
When I fitted a pair of GT tubi’s to my QP, I had a muffler builder weld in 4 pipes of about 10 cm to make it fit. So I would say that that is the only difference. The brackets are positioned in the same way for both models!
The 4.7 QP GT-S Auto and the 4.7 GT S MC-Shift certainly sound the same, and the mufflers look the same, so any differences are minor and possibly only refer to the shape/fit.
