Our exhaust tips are fabricated out of high quality stainless steel tubing and are hand polished to a high luster finish. To prevent water back wash, we offer models equipped with our Non-Burn internal flappers. Our rubber-tipped stainless steel Non-Burn design eliminates flapper burnout associated with butterfly type rubber flappers commonly found in lesser quality tips. Attention Boat Builders: We can custom build exhaust tips to your specification. Please call for a quote and delivery.
