BMW 340i/440i B58 Single Exit Catback Cen-Cal Exhaust – Valved & Track Editions

Elevate your BMW F30 340i or F32/F33/F36 440i with the Cen-Cal Single Exit Catback Exhaust, engineered for enthusiasts seeking performance, weight reduction, and a distinctive exhaust note. Crafted from premium T304 stainless steel or Grade 5 titanium, this system offers a significant weight savings over the OEM setup—up to 28 lbs lighter with the titanium version.

Choose between two configurations:

Street Version (Valved): Features an integrated valved system controlled via the included remote, allowing you to switch between a subdued tone for daily driving and an aggressive exhaust note when desired.

Track Version (Non-Valved): Designed for maximum performance and sound, this version eliminates the valving system for a consistent, unrestrained exhaust flow.

Each system includes a resonator in the midpipe to reduce rasp and drone, ensuring a clean and deep tone. The exhaust is TIG welded for durability and precision fitment.
