Dinan Free Flow Stainless Steel Performance Exhaust with Black Ceramic Tips for BMW 328i/428i (F30 F31 F32 F33, 2012-2015) - Twin 70mm, No Drone, Bolt-On

Dinan Free Flow Stainless Steel Exhaust with Black Ceramic Tailpipes for BMW F30 F31 328i and F32 F33 428i

Give your BMW 3 Series or 4 Series the soundtrack, response and finish it deserves. The Dinan Free Flow rear section is a premium stainless steel performance exhaust for F30 F31 F32 F33 models that unlocks a deeper, richer tone with impressive refinement inside the cabin. Acoustically tuned to minimise low rev resonance, it delivers a confident growl under load while remaining civil on the motorway. Expect a measurable uplift of up to 4 bhp and 3 lb ft, plus a stealth OEM plus look thanks to twin 70 mm ceramic black tailpipes with laser etched branding.

Crafted from 100 percent 16 gauge 304 grade stainless, this system is built to resist corrosion and stand up to daily use. It is a direct fit replacement that utilises factory style mounting points and comes with the required hardware for a straightforward bolt on install and factory like alignment. Dinan’s engineering focuses on smooth flow and reduced back pressure, helping throttle response and driveability without introducing unwanted boom.
