Yes, exactly! The bolt that the oil filter threads on to.Once you do the swap you can run the equal length. My car is driven every day since the conversion and it runs perfect! Well worth it!
Hey Timothy, the parts needing removal are adapter plates. These plates cause interference with clearence with most, if not all, Equal Length Headers. The 06-07 WRX has a different design. What they are needed for? Other than being adapter plates, not sure. It seems most aftermarket EL manifolds have this same problem when adapter plates and you're good. I found some info on PERRIN'S findings. Hope this helps you out..👍 Since the 04 STI was released with the oil pan with the large cut-out on the right side, this allowed us added room to create a smooth transition of the header primaries to the collectors, and collectors to uppipe. The problem is not all cars have this oil pan, and some cars do not have the same oil cooler to allow the PERRIN Header to fit. This affects the 2002-07 WRX and there are a few things that need to be modified in order to allow it to fit. Below is the info and part numbers needed to help guide you through the necessary steps to get the PERRIN Equal Length Header installed on your 02-07 WRX. For the 02-05 WRX (2.0L engine) the modification is simple. You need to replace your oil pan and oil pick up with the parts from a 2004-2014 STI. Besides the installation being a bit messy, this is not a very hard job to do. A DIY'er might take 4 hours total with cleaning and reinstallation. For the 06-07 WRX (2.5L engine) the car has the correct oil pan, but Subaru installed a weird oil cooler. These cars come with an oil cooler that is angled back toward the rear of the car, which causes interference with our header. These cars you need to purchase the oil cooler, and oil feed pipe from an 02-04 WRX or 04-14 STI. These cars require quite a few things to be removed, see the below diagram.
by the oil tube connector you mean the bolt that holds the oil cooler on correct?

Sorry, the diagram I attached didn't post. Go to Perrin's site and you can view it..
