The 7-axis CNC bending process achieves approximately 98 percent roundness to minimise turbulence, while direct spot welding and overlapping welds ensure long-term strength where heat is highest. The result is a GTI catback that fits like factory, breathes better and sounds superb.\n  \u003c\/p\u003e\n  \n  \u003ch3\u003eProven results\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003ePower gain: +6.2 Ps at 4823 rpm\u003c\/li\u003e\n    \u003cli\u003eTorque gain: +12.75 Nm at 3287 rpm\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003cp\u003e\n    Expect crisper response and a richer EA888 note without harshness or interior boom.\n  \u003c\/p\u003e\n  \n  \u003ch3\u003eOPF and GPF information\u003c\/h3\u003e\n  \u003cp\u003e\n    Running a petrol particulate filter.
