I've been doing some research on these forums and was wondering if any a5 3.2 owners installed an aftermarket exhaust with a non s line bumper. I want to know your opinions on those exhaust. Most of the exhaust systems i've seen show a quad tip or oval tip and I'm not about to spend 1K+ to swap out bumpers and valence to fit a quad tip exhaust. I've seen and heard the A5 StaSis exhaust on youtube, I like how it sounds, but, from reading these forums, there is alot of cabin drone. I have some reservations about getting the StaSis exhaust. I'm not sure if I want to ride in a noisy car just for a better exhaust sound.
