Constructed of robust 2mm thick 304 stainless steel, this 4 to 3 Inch Reducer has a gradual radius profile for efficient flow of exhaust gasses.

The smooth transitional shape is superior to the typical hard angle of similar reducers that can cause exhaust gasses to tumble, which reduces performance.
