IN STOCK READY TO SHIP!

True 4-Inch Catless Downpipe for the B46 engine. This downpipe features a 4-inch diameter all the way until after the flex pipe for maximum exhaust flow. It will bolt up to your stock exhaust but if you want a 4-inch custom exhaust all you need to do is cut right after the flex pipe and weld for a true 4-inch turbo back! 

No more fiddling with seized OEM clamps! Everyone has heard horror stories on how the oem clamps make installation a huge pain because they are often seized and due to their poor design it results in annoying exhaust leaks. When you purchase a downpipe we include a free aftermarket 3 inch v-band that will make installation much easier and ensure no exhaust leaks!

WHAT'S INCLUDED:

1x B46 4-inch Catless Downpipe

1x 3-inch v-band clamp 

OPTIONAL:

1x "Heatshield Products" Lava Exhaust Wrap (KEEP YOUR ENGINE BAY COOL!)

1x Downpipe to Turbo Gasket (Required everytime you swap downpipes)

Biggest downpipe currently on the market and we have found our design gives a better tone than the smaller diameters from our competitors. 

 

FITS THE STOCK GEN 1 B46 and Gen 2 B46TU EXHAUST! All B46 230i 330i 430i 220i 320i 420i
