By eliminating the restrictive catalytic converters in the factory downpipes entirely, backpressure is significantly reduced, resulting in faster turbo spool, a genuine increase in power, and a noticeably more aggressive exhaust note.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eRather 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 304-grade stainless steel tubing, they include a lifetime warranty alongside a \"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 note:\u003c\/strong\u003e this is a fully catless (decat) design.
