Dinan Free-Flow Axle-Back Exhaust System for BMW F30, F31, F32, F33, F34, and F36 Models with 2.0L B48 Turbocharged I4 Engine

Description

Dinan engineers designed the BMW 330i/430i exhaust to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. Like all Dinan exhausts our 330i/430i Free Flow Axle-Back Exhaust is engineered to reduce low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone.

The system is built with ease in mind and utilizes a simple bolt-on installation with included mounting hardware. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to come. The design features twin 3″ ceramic black or polished and laser engraved exhaust tips for a tasteful, high-performance look that yields a maximum performance gain of 4 horsepower and 3 ft-lbs of torque. The factory computer-controlled exhaust valve is eliminated.

Features:

• More Power: + 4 HP @ 6600 RPM, + 3 LB-FT @ 6600 RPM
• Drone abatement technologies used to reduce cabin resonance
• Enjoyably louder, sportier sound
• Twin 76mm (3″) laser engraved, polished or ceramic black exhaust tips
