I have an Audi TT 2001 and I'm trying to see what the best option for me to do is , I want to tune it and make it fast and what not, but I don't know if it's worth it, it a fwd and 135kmiles on it, 180hp , 5speed manual... What are ur suggestions.... And if I'm buying an exhaust and intake does it matter if it's a Quattro intake or exhaust...
