CTS Turbo F2X/F3X 228i/328i/428i & xDrive N26 High-Flow CAT

Open up your N26-powered BMW with the CTS Turbo high-flow cat. Built to drop in where the restrictive factory downpipe sits, it maximizes exhaust flow for the highest power gains while keeping a high-flow 200-cell catalytic converter in the system for clean, streetable performance.

Why it works

• T304 stainless steel, TIG welded and back-purged construction
• Replaces the restrictive factory downpipe with a high-flow 200-cell catalytic converter
• Precisely designed and tested on a real car in the real world
• Incredible sporty exhaust sound, subtle when cruising, no drone with factory exhaust
