The aFe Takeda 3" 304 stainless steel cat-back exhaust with center carbon fiber tips for 2017–2019 Honda Civic Si uses mandrel-bent tubing and dual free-flowing mufflers to improve exhaust flow. Hand TIG-welded construction and dual rear exits produce a deeper, aggressive tone while a reported gain of up to +10 HP and +11 lb-ft torque comes from the freer-flowing design and reduced backpressure.
