CTS Turbo Audi 8V S3 3" Turbo Back Exhaust

CTS Turbo's 8V S3 turbo-back exhaust is built by enthusiasts for enthusiasts, hand TIG-welded from the finest T304 stainless steel and engineered for both street use and big-turbo abuse. Where many 8V S3 exhausts choke peak power with 2.5"/2.75" tubing, this true 3" design is ideal for chasing serious horsepower.

Built right

Each downpipe is 100% TIG-welded from 3" T304 seamless stainless steel and includes installation hardware and stainless clamps — no seamed tubing that can crack and decay over time. It eliminates the factory downpipe, increases turbo spool and peak power, and the larger 3" diameter lets exhaust gases exit the turbo and wastegate with less turbulence for more power and torque across the powerband.
