The factory exhaust heavily restricts the true, aggressive character of the turbocharged B48 engine. Upgrading your exhaust hardware is an essential modification to unleash a deep motorsport tone while optimising gas flow for your F56. Remove the biggest factory restriction right off the turbo with high-flow exhaust downpipes. Transform your sound and drastically reduce back-pressure with premium Cat-Back Exhausts for non-GPF cars, or install emissions-compliant GPF-back exhausts for later GPF-equipped models. For a cost-effective acoustic boost, we offer GPF deletes and resonator deletes to remove restrictive silencers, alongside Misc Exhaust parts to ensure a perfect, leak-free installation.
