描述

Honda 400EX Phoenix Performance Exhaust Insert, replaces factory spark arrestor on your stock muffler. Not just a shiny endcap but a tuned perrformance insert! The length of the insert tube is critical to sound performance and exhaust flow: this insert protrudes intothe chamber of your muffler, using the design of the stock muffler to produce the best performance possible. Replacing the factory insert, these spark arrestor inserts simply bolt on using thesupplied hardware and factory copper seal. No drilling required, simply unbolt stock unit, and bolt on the power. What you get is performance equivalent to many name brand exhaust slip-ons. And, the sound is awesome, performance without being too loud. 10-15% power increase over stock when used with the recommended jetting andno airbox lid! Noise output tests between 91-93db.
