Change the sound of your Polaris Slingshot with this 3 baffle system adjustable exhaust by Fab Factory.
Fab Factory Adjustable Exhaust for your Polaris Slingshot.
This exhaust system is NOT for the tame of heart. This exhaust does NOT have a baffle and will be much louder than stock.
The new 2.5” catless exhaust system for the Polaris Slingshot, by Unified Performance, is fully TIG welded and back purged, made from the highest quality 304 stainless steel components available in the fabrication industry. This exhaust combines a straight flow-through muffler design to release exhausts gases as quickly as possible, but also uses engineered sound via its integrated Helmholtz resonator tube. This “anti-drone tube” not only helps to remove drone at given cruising RPM’s, but it also helps settle the unwanted tones common with free flowing exhaust systems. This exhaust is NOT for the tame at heart, under idle and cruise your Slingshot’s exhaust sound is present, however… talking or listening to music is of no issue. Under heavy throttle, your new UP tone exhaust is present and in charge!
We’ve had a lot of customers ask us about the lack of a gasket with the Unified Performance exhaust system. This is our intention! You should NOT be using a gasket with the Unified Performance exhaust system, here’s why:
The factory manifold mating flange and our exhaust flange are both flat machined surfaces. When they fit together and are torqued, there should be no leak. Our exhaust system has very little back pressure, and air flow will always take the path of least resistance, out the tip. Adding a gasket, which usually either overhangs into the flow internally, or allows a small void, (if the gasket ID is slightly larger than the flow path) causes turbulence and changes pressures at the flange mating point. This simple change in pressure can cause a leak just from having the gasket present. Once a gasket leak begins, hot exhaust flow will continue to tear up that gasket, until that gasket is burnt from the inside out. Once the gasket blows out, your exhaust is loose, flanges warp, and it’s very hard to get a proper seal again without re-machining the flanges.
This “lack of gasket” theory is everywhere in the turbo world these days. No big power turbo cars use a gasket between the exhaust housing and the exhaust manifold (T3, T4 mating flange etc) for this same reason. In the turbo instance, considerable internal pressures are present as well (unlike our exhaust) yet still do not leak. If both mating surfaces are true and flat, they will seal!
