Hello everyone! So first I want to say I’m new to the Audi car game. I switch over from American muscle N/A. I’m new to having a turbo also. I need some help with my Audi lol. I have a 2010 Audi TT 2.0t Quattro (s line) not sure if that matters but I need help with turbo noises! Looking for flutter and such not performance. I’ve been reading to install a cold air intake, Catless downpipe and muffler delete? Is that what I need to do? Any tips/tricks that help? Anything would help! Again I’m new to foreign cars
