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


The IE downpipe replaces the majority of the factory exhaust from the turbocharger all the way back to the factory exhaust just before the rear axles. The downpipe section includes a new mount bracket and utilizes the factory mount points along with a tough interlock core flex section, this allows engine and chassis movement without stressing or cracking your downpipe. Easily connect the downpipe and catted mid-pipe using the simple and strong v-band connection. Finally, the mid pipe mounts to the stock rear exhaust with the included 3" to 60mm slip-fit sleeve, or easily adapt it to your cat-back exhaust of choice. In-house digitally scanned and designed for an exact fit and includes all hardware to make the install easy and straightforward.
