Dinan Free Flow Axle-Back Exhaust for BMW F34 F36 340i 440i B58 — Overview

Dinan's axle-back replaces the restrictive stock muffler section on F34 Gran Turismo and F36 Gran Coupe 340i and 440i models running the B58 straight-six. It bolts onto the factory mid-pipe, so you keep the OEM catalytic converters and mid-section intact - straightforward swap that does not require tuning. Worth noting: the Amazon listing calls this an axle-back, which is accurate to the fitment, so if you came here expecting a full cat-back with new mid-pipes, this is not that product. It works with the stock hangers and exits through the factory rear valance cutouts.
