Armytrix Exhaust
 

Hi everyone,

I've been slowly comparing different exhaust options for my 2.0T A5 trying to find one that actually makes a difference with how the car sounds and of course, as much performance i can get, although small.

I recently stumbled upon a company with the valvetronic system, Armytrix.

Was wondering if anyone has any info on them, quality, sound, performance, and how it compares to the common, awe, apr, billy boat, etc.

Thanks!!

Grinding noise
 

Hey guys I just bought my first used Audi S4 2004 Quattro with a V8 4.2L. When I'm going slow and turn hard to the right or left I hear a vibration noise. It feels like it's coming from the all wheel drive on the front wheels. Is this normal for Quattro's or should I have it checked. U-joint maybe??

Thanks..
