So you're looking to get a little more growl out of your ride, huh? This Granatelli electronic exhaust cutout system is the way to go. It's not some cheap piece – it's built with a CNC-machined 6061 aircraft-grade aluminum body, stainless steel butterfly plates and blade shafts, and the whole thing is controlled by their \smart chip\ motor. What's cool is you just tap the included rocker switch once to open or close it. No holding it down and wearing out the gears. The polished stainless steel turndowns have a 45-degree slanted discharge and they can rotate a full 360 degrees with the V-band clamp, so you can point the exhaust wherever you want. It's a 2.5-inch (63mm) slip-fit system, and that high-torque DC gear motor makes sure it opens and closes all the way, every time. Perfect for when you want to be loud on demand and quiet when you need to be. Seriously upgrades the fun factor.
