BMW N55 Downpipe

Welcome to WeldAffection — brilliantly designed by taking the best assets of our original Downpipes and adding new design features, we have achieved the ultimate goal: performance.

We are proud to introduce our WeldAffection product for your BMW.

WeldAffection Downpipes are a direct fit with no modification required. Our decatted Downpipes are fitted with OEM flanges and fittings to allow an easy, trouble-free installation.

Upgrade to the BMW N55 Downpipe to eliminate the backpressure caused by your stock catalytic converters. By upgrading to our Downpipe, your turbo can now spool faster and achieve maximum power. As a bonus, your car will sound a lot nicer as well.
