I am considering putting a chip and exhaust into my 2004 S4. It has great power but with a little bit extra I could smoke an M3. Does anyone know what chips and exhaust systems are most reliable and provide the most power?

 

chips? eh, you're not gunna feel a huge difference since you cant much out of a naturally aspirated car

full exhaust is the way to go

 

i've been wondering this same thing and i found this xpost tonite. http://www.audiworld.com/news/05/b6dyno/content.shtml

it includes the full back with the chip, but +22 at the wheels should be a nice feeling. i'm just not sold on miltek. i like the sound of lebree; but i need to see if it also helps the numbers like the miltek.

 

22 at the wheels is damn good

 

I've had my miltek system for about 9 months. Really like it. Probably a bit more subtle than Labree.

 

Go with Labree....loud pipes save lives.

 

The V8 isn't easy to get a ton of power out of like the 2.7, but I'd go with the exhaust and see what you get out of that. To get any major power you are going to have to go with motor work. Cams would probably be the easiest noticable gain but I don't know who offers them for the newer cars.

 

Mod all you want, but unless you SC your car you will still struggle to stay w/ an M3.

 

? i wouldn't say struggle. the two are fairly equals when you duke them out for acceleration, braking and handling ( as a bundle package not separately)
