Putting my 2017 S3 back to stock in order to sell it. I have a CTS Turbo cat-back on it now. Unfortunately I didn't keep the stock exhaust so looking to pick one up. If someone was looking to go aftermarket I'd also be interested in a trade plus cash (on the buyers part), as long as you were in SoCal and we could have the swap done locally. i had custom built mounts put on with the exhaust to have it seated perfectly with no movement. Shoot me a PM if interested.
