This GrimmSpeed adapter will allow you to adapt and properly seal an aftermarket 3-inch downpipe to a 2.5-inch OEM or OEM-like catback exhaust. This adapter only works with a flared end and it creates a smooth transition from your 3" inch aftermarket downpipe to your OEM midpipe. The end was flared out just shy of 3 inches so it does not block flow! With the ability to work with both flat style gaskets and donut gaskets, this adapter cannot be matched. CNC laser-cut steel construction Provides a leak-free seal and smooth connection Designed with a flared adapter transition Flanged for an OEM donut gasket Will not obstruct exhaust flow Flared end guarantees smooth exhaust flow Includes installation hardware Simple bolt-on design Sold individually
