Upgrade your Volkswagen MK7 GTI with the CTS Turbo 3" Catback Exhaust. This catback exhaust was engineered to improve exhaust flow, deliver a deeper exhaust note, and support higher horsepower applications without sacrificing daily drivability.
The factory exhaust system uses smaller-diameter piping that can become restrictive as power levels increase. The CTS Turbo catback utilizes true 3" mandrel-bent T304 stainless steel tubing to reduce exhaust restriction, improve flow efficiency, and create a more aggressive exhaust character while maintaining a refined cruising experience.
Quick Fitment Overview
- Compatible with Volkswagen MK7 GTI (2015–2017)
- True 3" resonated stainless steel catback exhaust system
- Designed for stock turbo and big turbo applications
- Includes adapters for factory and aftermarket downpipes
Product Description
The CTS Turbo 3" Catback Exhaust is designed for enthusiasts seeking improved exhaust flow, premium construction quality, and an aggressive yet refined exhaust tone. Constructed from hand TIG-welded T304 stainless steel, the system features CNC mandrel-bent tubing that maintains consistent diameter throughout the exhaust path for maximum flow efficiency.
Unlike many competing systems that utilize smaller 2.5" tubing, the full 3" design helps support increased airflow requirements for tuned and upgraded turbocharger setups. The resonated configuration produces a deep performance tone under acceleration while remaining comfortable during highway cruising with minimal drone.
