I have a 98'A4 2.8 Tip. The gas pedal of this car seems very sensitive. Being a car enthusiast, I would like to make my car go faster and sound better. So I replaced the K&N drop-in air filter on my A4 and added a Remus exhaust.

The acceleration "feels" very responsive with the set up of K&N filter and Remus exhaust. The sound of the exhaust is pretty quiet at idling compared with Japanese brands, but once you hit the "sweet" spot between 3000-6000 rpm, the deep tone from Remus is making you feel like this car got least 250 hp.

I raced with my friend's stock 2000 325i auto. From 0-60 mph, we were about the same, as soon as my A4 reached to about 70 mph, it just pulled ahead at least half of the car length. The filter and exhaust really help the car's acceleration at mid and high rpm.

I would recommend this combination to anyone who owns an Audi.
