CTS Turbo MQB FWD Exhaust Downpipe with HIGH FLOW CAT (MK7/MK7.5 Golf, GTI, GLI, A3 FWD)

This CTS Turbo 3.5" high-flow cat is built for front-wheel-drive MQB cars — MK7 GTI (incl. Performance Pack), MK7 GLI, MK7 Golf 1.8TSI (incl. FWD Sportwagen), MK7 Beetle 1.8TSI, MK3 Audi TT (FWD) and 8V Audi A3 1.8TSI (FWD, not Quattro). The factory downpipe chokes power once you are chipped; this one smooths flow to release it, and looks great in the process.

A modular design keeps catalytic-converter installation simple, with CNC-machined flange and smooth transitions for optimal flow.

A CEL will appear without proper tuning software, so stage 2 software is required, and CTS Turbo recommends a high-flow cat for the sake of the environment. The optional CEL eliminator greatly reduces the chance of a cat-efficiency code, though it is not 100% effective.
