Any suggestions for an 05 S4

I just bought an Audi S4 and I was curious if there any mods that are just necessary to have when it comes to Audi S4s. I know this car has power and I want to make sure all M3s know it.

chip and exhaust and you'll eat M3's for lunch. ok, you won't eat them but you'll at least have a taste of victory instead of the M3's exhaust fumes.

thx. do you know if that will void the warranty.

changing any computer componet to alter engine output will def. void warranty

A chip will void warranty but you can get a stock mode which is a mirror image of stock and they will not know anything. The exhaust will not be an issue as it does not affect anything that could go wrong. There is always brakes and suspension for teh car too! It also depends on your dealership. I work for an Audi/Porsche/VW tuner company and we do a lot of work with the local dealers including pre-tuned new cars. I cant say which company I work for on here because we are not paying advertisers. I will say this, with a little work, you car will be AWEsome!

have fun with it!
