READY FOR STAGE 2 POWER? When upgrading your VW MK7 Golf R or Audi 8V S3 to stage 2 software you will also need to reduce the back pressure caused by the small diameter stock pipe. With the exhaust system flowing better performance gains are achieved, sound is increased, and turbo lag is reduced. IE engineers guarantee a perfect fit by designing all IE downpipes in-house using the latest technology. Digital scanning is using to scan the entire environment which ensures that there is proper clearance and that all mounting points are in the correct location. Manufactured from 304 stainless steel offers a life-long product that brings performance and fun to the table for years to come. Stage 2 ECU tuning is required, for the most power gains possible we also highly recommend an IE air intake and IE FDS intercooler. MOTORSPORT SOUND: An aggressive and drone-free sound will be emitted from the IE Cast Downpipe giving your car a true motorsport feel. Thick wall tubing and cast sections remove much of “tinny” sound and annoying exhaust drone emitted by cheaper, thin wall, downpipes. With downpipes, you get what you pay for in terms of sounds and overall manufacturing quality. HIGH-FLOW CATALYTIC CONVERTER (CAT): IE’s MQB 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. OPTIMIZED 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 withou
