I've finally decided on what exhaust I'm going to run. With APR's sale on at the moment, I've chosen to go with the APR stealth, & am going to change to the R1 diverter valve as well. Will get them next Monday, & then I'll post with my impressions.

 

How much for the exhauast? Have you heard APR's exhaust before? Last time I saw a video of an A4 w/APR exhaust is sounded pretty raspy and unappealing imo.

 

Haven't you ever seen the A4 build upon Sports Car Revolution? It's on the APR website. I want an exhaust that is understated, but has H.P. gains, I don'twant anything that sounds ricey

 

My bad, Im thinking of the B5 APR exhaust. It sounds different compared to the B6 version. Milltek falls into the understated category, give them a look if you havent. Prices are usually the highest of any of the exhaust makers though.

 

The Milltec exhaust is smaller. it might sound good, but want a larger system to help with the larger injector flash that is in the future.

 

What is the diameter? Mine is 2.75 but it might be different for the B6. Thats usually the max you should go without having a bt.
