BMW Catless Downpipes are now available at Bmwmpower247 through VR-Speed Factory!

Downpipes are a must have when adding power to your build and is also a requirement when running Stage 2 on Bootmod3 or MHD!

All items are shipped directly from VRSF. Adding a downpipe will not only increase airflow through the exhaust, but will increase power, deepen/louden the sound (as well as make the spooling of the turbos more prevalent to the ear!).

The B58 downpipe is 4.5" and constructed from stainless steel 

E9X N55 is 3.5" and comes ceramic coated

E9X N54 is 3" and constructed from stainless steel (V2)

S55 is 3" and constructed from stainless steel

F series N55 before 7/13 is 3.5" and constructed from stainless steel

F series N55 after 8/13 production is 4" and constructed from stainless steel

Each downpipe will be without catalytic converters (catless) and is for off-road intended use only.
