By eliminating the restrictive catalytic converters in the factory downpipes, backpressure is significantly reduced, resulting in faster turbo spool, a genuine increase in power, and a more aggressive exhaust note.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eHand-crafted from mandrel-bent, TIG-welded 3in stainless steel with smooth radius bends to decrease turbulence and increase flow, these downpipes are specifically engineered for the 335xi's AWD-specific exhaust routing, distinct from the standard rear-wheel-drive N54 downpipe. Grade 12 installation hardware and mid-pipe gaskets are included with purchase, and VRSF's mounting hardware has been upgraded to Grade 12 nuts and bolts across the board, a significant upgrade over the original Grade 8 bolts at no additional cost.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWorks with:\u003c\/strong\u003e Both RHD and LHD models.
