I have a S2 R33, it came with a AVO Stealth Front Mount (pretty sure its AVO) using stock piping, same as these Just Jap ones. However they needed to remove a very small part from the front bumper. If you are looking at the car from the front, the right hand side pipe that comes off the cooler. So small can only see it when really close up.
Great thing is thats its a black intercooler, so its super stealth. Lots of people ask me "When you going to get a front mount?" which is a great sign for a sleeper look.
not sure of the dimensions of the cooler, looks same size as the Just Jap ones. Not even sure if they still make them, but might be another option for you guys cnsidering the Just jap one.
Hope that helps, cheers
