I was in the middle of installing an exaust manifold made by XS POWERS VW / Audi KKK Turbo Manifold, Audi Turbo Manifolds, XS Power Inc.
Which states it's a bolt on upgrade. It took me about 1.5 hours to remove the stock manifold just to find out the flange is right in front of port 3 from the driver side to passengers side. However the original one is In front of port 2. I have been sending emails to the vender but no response, now for my question, I was really looking forward to adding an aftermarket manifold to squeeze out as much h.p. as possible what other manifold is recommended for this application. This is for a 2001 Audi tt base model.
