Ok everyone. I have a 2000 A4 1.8T Quattro. With the tiptronic transmission. I found a Borla exhaust for $615.00 plus $117.20 for shipping. I would like tp have more than option when buying my exhaust. I was willing to pay the 6 but I am not sure about the 750. I have found that alot of them say this exhaust is for manual transmissions only. Or this will only work with automatic transmissions. The Borla it the only one that says tip. Any help would be greatly apreciated.
