Just thought that I would let everyone know that I e-mailed Juan and was told that the Vibrant catback exhaust system would be too restrictive to work with the Hi-Boost system since it has a 60 mm diameter.  He said that if you were going to run the Hi-Boost setup you would need an exhaust system with a 70 mm diameter pipe which would be about 2.5".
