This equal length Z pipe routes both sides the same distance before they meet, so the pulses arrive together. The result is a cleaner, deeper note with far less of the metallic edge, and a car that sounds expensive rather than just loud.\u003c\/p\u003e\n\u003cp\u003eManufactured from mandrel-bent stainless steel and TIG welded throughout, it bolts to the factory locations and works with either the standard downpipes or an upgraded set.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003ch3\u003eEqual Length Z Pipe Design\u003c\/h3\u003e\n\u003cp\u003eBoth banks routed the same distance before they merge, equalising pulse timing and cleaning up the tone.\u003c\/p\u003e\n\u003ch3\u003eSignature S55 Sound Transformation\u003c\/h3\u003e\n\u003cp\u003eDeeper and smoother, with the factory rasp substantially reduced.\u003c\/p\u003e\n\u003ch3\u003eChoice of Resonated or Non Resonated\u003c\/h3\u003e\n\u003cp\u003eTwo builds, shown in the first two images.

It does not meaningfully restrict flow, but it takes the hard edge off the sound and is the difference between a car that is simply loud and one you can still hold a conversation in at 100km\/h.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNon Resonated — this is the system shown in IMAGE 1.\u003c\/strong\u003e Straight pipes through the mid-section, the loudest and most aggressive setup, with the sharpest S55 character. Best suited to a car that gets driven hard rather than commuted in.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eResonated — this is the system shown in IMAGE 2.\u003c\/strong\u003e You can see the two in-line resonator sections in the middle of the pipes. It gives a cleaner tone with far less drone at cruising speed, still considerably louder than factory but much easier to live with on a daily drive or a long trip.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease look at both images before you order\u003c\/strong\u003e so you know exactly which system you are buying.
