B7 RS4 resonator delete
Posted: Mon Feb 19, 2018 7:00 pm
Hi all. Picking my new B7 RS4 this Friday and one of the first things I want to do is take out the resonator. I did this on my A45 AMG and I can’t tell you what a difference it made so can only assume the same will happen there or there abouts to the RS4. Can someone tell me what size stainless pipe to buy and how long? Can it be butt welded or does it need to be sleeved. I can get a piece bought ready for delivery. Thanks.
