Brand new pair of Sinister Products LLC 4 Inch Straight Exhaust Tips. 10 Inches overall, approximately 5 inches in, and 5 inches out the transom of the boat when installed. Tips are completely unbaffled for maximum performance. These exhaust tips are made entirely fom the highest quality 316L 8k Mirror Polished Stainless Steel, unlike alot of our competitors that use a cheaper 304 grade that isn't designed to fully withstand marine conditions. 316L grade stainless steel is the most desired alloy in the marine industry today. It possesses the longest finish and corrosion resistance for it's environment. All tips are constructed from heavy duty .060 thickness 316L Stainless Steel tube, and an extra thick .080 CNC cut flange. These tips are fully welded on the back of the flange to prevent water intrusion, instead of the typical spot welding seen by competitors. All transom mount holes are chamfered to allow for a much cleaner install. These are extremely high quality exhaust tips, with an incredible finish for less than half the cost of other name brands.
