Our system merges both banks into a large 3.5” single section, allowing the exhaust pulses to interact earlier and more evenly.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis single-pipe configuration helps reduce high-frequency rasp while producing a deeper, smoother and more defined exhaust tone. The increased tubing diameter also provides a less restrictive flow path than the factory midsection, making it suitable for both stock and higher-output vehicles.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSmooth transitions throughout the system help minimize turbulence and unnecessary changes in cross-sectional area.
