I have an S4 full catback exhaust lined up and I'm looking at custom piping / S4 stock exhuast setup on my A4 1.8T K04 setup - I need miniumum 2.25".

Why am I doing this? need quiet! so even the borla may be too loud for me!

thanks all

"There seems to be many misconceptions about the stock exhaust tubing size. The exact tubing size of the S4 cat back exhaust is 2.157" in english units, this is also the I.D. size of the stock couplings."
