Upgrade your Volkswagen MK7 GTI with the CTS Turbo 3" Turboback Exhaust with High-Flow Cat, engineered to maximize exhaust flow, improve turbocharger efficiency, and unlock additional horsepower and torque throughout the powerband.
The factory exhaust system restricts exhaust gas flow immediately after the turbocharger, limiting performance potential on both stock and tuned vehicles. This complete turboback system replaces the restrictive factory components with a true 3" T304 stainless steel design, allowing exhaust gases to exit the turbo more efficiently while producing a deeper and more aggressive exhaust note.
Quick Fitment Overview
- Compatible with Volkswagen MK7 GTI (2015–2017)
- Complete 3" turboback exhaust system with high-flow cat
- Improves turbo spool, horsepower, and torque
- Constructed from T304 stainless steel for durability and corrosion resistance
Product Description
The CTS Turbo 3" Turboback Exhaust System is designed for enthusiasts seeking maximum exhaust flow and performance from their MK7 GTI. By replacing the restrictive factory downpipe and catback assembly with a larger-diameter performance exhaust system, turbocharger efficiency improves significantly, helping reduce backpressure and allowing the engine to breathe more freely.
The high-flow cat offers a performance-focused solution that improves exhaust flow. Combined with a true 3" exhaust, the result is faster turbo spool, stronger midrange torque, improved peak horsepower, and a refined performance exhaust tone suitable for both daily driving and enthusiast use.

Frequently Asked Questions
Q: What are the benefits of a turboback exhaust compared to a catback system?
A: A turboback system replaces both the downpipe and catback exhaust, providing significantly greater exhaust flow improvements and performance gains.
Q: Does this system require tuning?
A: Yes. Stage 2 ECU tuning is required to avoid a check engine light.
Q: Will this increase exhaust sound?
A: Yes. The system produces a deeper, more aggressive exhaust tone while remaining refined during highway cruising.
