The J-line is askew. Meaning the inlet & outlet are not centered. If you flip the IC they will be closer into the car and clear most of the small plastic around the hoses. However, I also used 4" HPS cuplers and not the OEM as the don't reach quite right along with Cobb IC pipes. I cut the 2" off the top to expose more of the IC; quite worth it IMO as the car looks even more aggressive.
