{"product_id":"vrsf-bmw-s63-f90-m5-f9x-m8-catless-downpipes","title":"VRSF BMW S63 F90 M5 \/ F9X M8 Catless Downpipes","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThese downpipes are the best bang-for-buck modification available for the M5 or M8, with genuine gains of 112hp and 130tq when tuned. 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\"\u003eThe F9x M5 and M8 have 2 primary and 2 secondary catalytic converters, 4 total. Depending on which configuration you choose, you can retain the factory or aftermarket components on whichever pair you don't replace, giving you genuine flexibility in how far you want to take the upgrade. Rather than necking down closer to the turbos the way most competitor downpipes do, these feature a smooth mandrel-bent design for a significant increase in flow. Hand-crafted from SS304 stainless steel with CAD\/CAM-optimised CNC flanges, they include a lifetime warranty and VRSF's \"No Hassle\" satisfaction guarantee covering fitment and defects.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003ePlease select your configuration at checkout:\u003c\/strong\u003e Primary Race Downpipes only, Secondary Race Downpipes only, or Primary \u0026amp; Secondary Race Downpipes together.
