The result was a much better sounding exhaust overall. The factory cat back has a very unpleasant rasp when used with a downpipe which does not have a resonator. As IE engineers are true enthusiasts as well, it was very important that the exhaust also sounded great.

Using specialized 3D scanners and software, IE engineers can design odd shapes and sizes to maximize flow and conform into tight spaces without any sacrifices. To accomplish these shapes, sections of the dowpipe are cast manufactured from the digital models.
