Hi all, I have been reading a lot on this forum and others on exhaust mods for my 2005 Quattroporte. I have the comfort windows (double glass) and so I would like to increase sound output from my exhausts a bit since with windows closed it is barely noticed below 4500rpm. I was wondering: the new QP Sport GT uses a valve to connect/disconnect the center resonator with the sport button. I believe the rest of the exhaust system is the same as the normal Quattroporte (believe factory installs Fuchs OEM). Would that be something that can be retro-fitted on my car? Any idea of cost? If not I could just remove the center resonator with a normal pipe like some of you suggested. I have read that would increase sound level by +/- 20% without affecting sound quality. Anybody has experience with this? Sound clip? I don't feel like spending another 6.000$ to change the complete exhaust system (Tubi, Kreis-Sieg etc). Thanks.....
By the way love my car just which the Sport GT was out when I bought mine....
