HIGH-FLOW CATALYST
IE’s performance downpipe includes a high-flow 200 cell per inch metal matrix catalyst located as close to the turbo as possible. Metal matrix catalysts are higher performance because the matrix web is thinner, allowing higher flow in the same size. Our catalyst is also a very large diameter, allowing a large flow area and maximum power. By being placed close to the turbo, emissions and unwanted unpleasant smells are greatly reduced.
QUALITY CAST SECTIONS
Typical aftermarket downpipes use bends or cuts to form the shape of the downpipe; this allows the use of larger piping, but sacrifices flow and often times fitment. 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. The result is an incredibly high-quality performance unit with a perfect fit and beautiful finish.
