VW Polo GTI (AW) Mk6 2.0 TSI EA888 2017+ OPF/GPF-Back (PPF-Back) Exhaust - Rear Box/Silencer Delete, Muffler & Backbox Delete,

Transform the sound and feel of your Polo GTI AW with a rear silencer delete OPF-back system

Looking for a deeper, harder hitting soundtrack from your 2.0 turbo petrol Polo without touching the catalyst or the particulate filter? This Cobra Sport OPF-back upgrade replaces the mid and rear sections and removes the factory back box for a raw, motorsport-inspired note that brings the EA888 alive. It is the perfect back-box delete for owners who want more volume, more character and crisper throttle response from their Mk6 hot hatch.

We have installed this system on customer cars and the feedback has been consistently brilliant. Expect a punchy tone at idle, a rich growl through the revs and proper crackle on lift-off, while keeping the GPF and OEM cat in place. If you are searching for Polo GTI AW exhaust upgrade, muffler delete, OPF-back system, rear box delete, silencer delete pipe or GPF-back performance system, this is the one.

Why this upgrade
