Just bought a 2020 glc63s almost fully loaded (PE!). Need help deciding on exhaust.
Looking at red star exhaust. Having trouble deciding between downpipes and the axleback they offer. Similar price, especially since I probably have to get catted and heat shield.
I've been told the downpipes will offer the best volume increase, with the added benefit of tuning later on. But I also read you have to take out the transmission to install these. Is any of this true?
If downpipes are louder, cheaper, and actually offer performance gains (with a tune), why would anyone get the axleback?
