Which exhaust system would be better for my 1999.5 1.8t A4
-milltek A4 1.8t 2.75" catback exhaust
-Borla rear exit catback system wiht dual rounded half-rolled phanton tips
-neuspeed dual slash tip styale 2.5 inch catback system
if anyone has any information on which would be the best that would help alot thanks

 

Personally, I like the way the Milltek sounds

 

I have a Milltek...my friends have Milltek. That will add 10-15hp, potentially. But...the best part is the way it sounds. It is the BEST. Deep, throaty, not ricey - at all - and not too loud inside the car. Sounds very good outside the car...your friends will hear you coming, but not in the annoying way.

Excellent choice. Quality materials with lifetime warranty too...not bad.

I got mine from Renn-Art in Arlington Heights, IL. They are great to work with!
