Scorpion Exhaust Resonator Delete & GPF/OPF Delete Mid Pipe for BMW M140i/M240i (F20 F21 F22) 2016-2020 - 80mm Centre Section, Fits OEM Back Box, B58, xDrive Compatible

Scorpion centre pipe upgrade for BMW M140i and M240i B58

Give your F20 F21 F22 B58 the soundtrack it deserves with Scorpion’s straight-through mid-section. This centre pipe replaces the factory centre silencer and, where equipped, the OPF particulate element, transforming track-day character while keeping the stock rear silencer for an OEM-plus finish. If you are hunting for a BMW 1 Series and 2 Series B58 centre pipe, OPF bypass tube, midpipe upgrade, or a louder M140i and M240i exhaust note without changing the back box, this is the proven choice.

Why enthusiasts choose this mid-section

• Centre silencer removal and OPF bypass in one assembly for a freer flowing exhaust path
• Noticeably more volume and a deeper, sportier tone on circuit compared with the restrictive factory centre section
• Large 80 mm 3.15 inch bore for excellent gas flow on the B58 platform
• Pairs with the original rear muffler for a clean, subtle look with a big sound upgrade
• Approximate 2.6 kg weight reduction versus the OE middle section
• Built by Scorpion for precise fit and reliable sealing
