It runs mandrel-bent raw 409 stainless piping into a centre hot dog resonator, then into an oval rear muffler with a dual outlet finished in twin 80mm tips. It is an easy bolt-on design, and it fits manual transmission cars only.\u003c\/p\u003e\u003cp\u003eThe order of the silencing is the part worth understanding. A hot dog resonator sits in the centre of the system, where the gas is still travelling in a single pipe and the frequencies behind rasp and cabin drone are easiest to absorb, so the rear muffler is not left to handle all of the quieting by itself - that two-stage split is generally what separates a deep note from a merely loud one. Mandrel bends hold their full internal diameter through the corner rather than pinching the cross-section, so flow stays even along the whole length and not just in the straight sections. The 409 is a ferritic stainless chosen for heat and corrosion life rather than appearance, and a raw finish is normal on pipework that spends its life out of sight under the floor.\u003c\/p\u003e\u003ch4\u003eFeatures\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRaw 409 stainless steel construction\u003c\/li\u003e\n\u003cli\u003eMandrel-bent piping for maximum exhaust flow\u003c\/li\u003e\n\u003cli\u003eCentre hot dog resonator\u003c\/li\u003e\n\u003cli\u003eOval rear muffler with dual outlet\u003c\/li\u003e\n\u003cli\u003eTwin 80mm tips\u003c\/li\u003e\n\u003cli\u003eBolt-on installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFitment\u003c\/h4\u003e\u003cp\u003eSubaru WRX with a manual transmission.
