This is a sensible middle-ground option for owners wanting a substantial flow improvement without going the full de-cat route.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eConstructed from T-304 stainless steel throughout, this system is built to outlast the factory components it replaces, resisting the corrosion that eventually catches up with mild steel factory parts. Reducing backpressure across both the downpipe and catalytic converter sections at once delivers a more complete performance upgrade than addressing either section individually, particularly noticeable when paired with a supporting ECU tune.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e our records show this part number (SSXAU901) originally listed against a 2020-2021 production window rather than 2020-2025.
