"I recently bought a few performance parts for my BMW from AutoTopNL, and the whole experience was top-notch. The website was easy to navigate, and they had exactly what I needed. Shipping was fast, and everything came well-packaged. The quality of the parts is excellent—definitely not cheap knock-offs. My car runs smoother and sounds better already. Would definitely recommend AutoTopNL to any BMW enthusiast!."

DESCRIPTION
This mid-pipe runs from the downpipes to the stock rear silencer, deleting the center silencer, secondary cats and OPF. This version contains an OPF sensor connector for the OPF hose. For use with OPF Deleter unit, coding or if you don't want to remove the OPF cables.
It converts the exhaust track from a double pipe into one. This results in a more full-bodied exhaust sound with a deep tone. Requires an ECU tune (recommended) or OPF deleter unit (Available here: https://autotopnl.shop/nl/products/leib-cat-and-or-opf-delete-kit-pro-for-bmw-g8x-m3-m4-competition?_pos=2&_sid=de5c14647&_ss=r )which removes the OPF fault codes (since it's gone).
