What options do I have to have a more aggresive exhaust note? I like to maintain the oval 2 flute pipe design of my C4, as far as I know that does not work with the Porsche sport exhaust (XLF) Right? Also, I would like to switch modes from normal to sport and back. ( Sensitive neighborhood ) My car has no Sport Chrono or PASM. Any idea and does it cost (USA)
Tx for your ideas and solutions.
