The Tecnigas Next-R is a proven and versatile exhaust system that already works great on original cylinders with good power delivery. This exhaust system provides improved acceleration with relatively low noise levels in the “deep tone” area. The Tecnigas Next-R exhaust system comes with a black anodized muffler using a steel and anodized aluminum expansion chamber, as well as all the necessary fittings and brackets. Next-R is not only a good design, but also long-term corrosion protection. Works well on standard or tuning cylinders.
