BMW N55 3.5" Catless & Catted Downpipe (135i, 335i & X1)
At ML Performance, we are proud to introduce you to the 3.5" catless downpipe for your N55 135i, 335i & X1. The 3.5" downpipe is the best value downpipe available on the market. By eliminating the restrictive catalytic converter in the factory downpipe, back pressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note.
The catless downpipe feature a full 3.5" stainless steel design and are hand crafted from SS304 grade stainless steel and includes the ML lifetime warranty. Grade 12 installation hardware and high quality steel gaskets are also included with the purchase.
You may also wish to add the N55 Downpipe Fix to remove the Check Engine Light.
Note: The N55 downpipe now comes with ceramic coated free of charge. We use Cerakote's best thermal barrier coating which helps keep the hot air inside the exhaust and out of the engine bay which decreases overall intake air temps along with engine and transmission oil temps.
