Alright so I just recently purchased an 07 a4 2.0t quattro and its stick and I really like it a lot but it just seems rather slow and I have heard there are things you can do whether it be get an ecu or upgrade the cat or downpipe but i just dont know too much about cars, specifically audis so i figured i would try this out and see if anyone who has a lot of experience could help me out and give me some advice on what is out there and what can make my car actually fast.

 

Welcome to this forum, i'm also relatively new, never done modification to my car, but i think here you'll find people who can help you with what you need for your new a4
