Built in 3\" (76.2mm) T304 stainless steel with a centre H-pipe, it gives a deeper, more aggressive sound under load.\u003c\/p\u003e\u003cp\u003eThe factory valve motors are retained, so the drive modes still switch between a quieter tone in Comfort and the full sound through all four tips in Sport and Sport+.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e This system removes the secondary catalysts and is sold for motorsport \/ off-road use only - it will not pass a UK MOT emissions test.
