Keep in mind this is a S3 don't try to get a ton of top end out of it. It just does not have alot of top but its a beast on the bottom.
x2 plain and simple. you can make it work but wont be smooth
. 086 or 053. great price and perfect match. 2020 or 2045 will be strong pipes but wont get the runtime of 086 with stock long header
